The Corsairs list is primarily a shooting based army, you have widespread access to long ranged S8 and S6 shooting, can do MSU incredibly well and have a Solar Pulse equivalent on the Prince. You should be avoiding combat unless you can absolutely help it, everything is S3 which even with Power Weapons isn't very scary and unlike a Craftworld list you don't have Doom to back it up.

From the top:
The Prince is easily the best HQ available,(the Void Dreamer is hilariously bad) but really doesn't need much gear, where you have him is as high as I would go points wise. Despite having access to a Shadowfield you can't use him as a combat character since he can't get an Agoniser type weapon or some way to boost his strength (Drugs/Huskblade) while maintaining his power weapon (5 S4 Rending attacks isn't much, you can almost get that from a 15pt Razorwing, who is basically as tough as well). He is always going to be a S3 T3 character without Eternal Warrior, he dies to just about everything so throwing him into combat should always be a last ditch effort. His best ability is the Nightfight missile, which is basically a Solar Pulse in an army which can spam 36-48" range shooting (unlike Necrons who are a 24" range army). Also remember that he can Deep Strike things in, which is a decent way to use a 80pt Fire Dragon unit if you aren't using the Aspect slot for anything else.

The Command Squad really doesn't threaten anything unfortunately, its supposed to be an elite assault unit but they only have WS4, are seriously let down by S3 and to top it off they are incredibly fragile. Imo the best use for them is as a 28pt unit to unlock another Venom, at which point you could give them Fusion Pistols I guess (its a real shame they can't get Fusion Guns).

Considering they are only 5pts more you should always take EML over Cannons in any Corsair unit. You are fragile but mobile, so play the range game from outside 24" and JSJ into/behind cover. I wouldn't bother with Flamers on these guys, you really don't want to get in close unless you don't mind losing the unit (which is fine for a 50pt 5 man unit, but not a 150pt 10 man unit). Tbh I would stick with the Lasblaster on these guys though the 24" reach is far more powerful than the extra point of strength. It can be worth giving them Fusion Guns though, since you can move and fire everything any vehicles which get too close are going to take 4 S8 shot to the face.

Its unfortunate, but you have no way to get a second Fusion weapon into the 5 man units to make them reliable melta hunters without resorting to Fusion Pistols. Tbh if you can get your Melta/heavy anti tank elsewhere (see Warp Hunters, Dragons) then you would be better off just taking a Missile Launcher for the same cost and just sitting back.

I would never take Holos on a Venom, it almost doubles the cost of the vehicle and you really don't get much use out of them on an open topped AV10 vehicle. Yes it makes you really easy to kill, but you really just have to accept that and use the list as best you can.

I'm very much on the fence with Wasps. They give you more firepower for relatively cheap, but they take up valuable Troop slots which you tend to need with such a fragile army and unlike Craftworld Eldar you can actually get some decent scoring units. The real issue is that they cost the exact same as Hornets, who are AV11, much much faster, have Scout and don't take up a scoring slot.

As I just mentioned, Hornets are amazing units, they are easily the best Fast Attack unit in the list or even the overall Eldar list and would have to rank close behind Dragons as the best unit available to Eldar. Even with no upgrades they are very effective, they are 5 points more than an equivalent Vyper with double Cannons and have +1AV, BS4, Scout (so the 24" range is never going to be an issue) and can move 12" and fire everything. Taking 6-9 of these to provide your S6 anti infantry needs is a very solid tactic, since they can get in your opponents face and keep them away from your more vulnerable units (the same way as Vypers do, just with more firepower and durability).
Alternatively you can tool them up, tbh I wouldn't bother with Scatters (Cannons do the job), Starcannons (again Scatters or Cannons do the job better for cheaper) or Bright Lances (just take Pulse Lasers and use melta to kill heavy armour). Missiles lets you do a Missile spam list pretty effectively, 20pts more than a Typhoon for Scout and AV11. Pulse Lasers are also worth considering, even a single Hornet for 125pts is on par with a Vendetta as a ranged tank hunter/heavy infantry killer and isn't up on the massive flying base waiting to die (and is tiny so can be hidden as well).
With vehicle upgrades Holos are really the only one worth considering, in squadrons you don't need Stones and probably should be kept cheap as forward movement blocking units so you don't take Holos there. If you are running Pulse Lasers you could conceivably be running around by yourself, and with Pulse Lasers you are already the price of a Serpent/Prism/Night Spinner anyway to the Holo can be worth it.
Either way I would pretty much always be filling up my Fast slots with this list, at 65pts its hard not too.

While its clearly going to be hard to fit everything in to 1500pts the big unit you are missing is the Warp Hunter. I used to describe them as mobile D-cannons, but with 36" range and a Large Blast rather than a small Blast they are much much better than a D-Cannon. Large Blast and the fact that you only need to clip to do damage (i.e the position of the hole doesn't matter) means you can easily hit multiple vehicles at once. Being able to remove heavy infantry on a 2+ is incredibly powerful, particularly in an army which can otherwise spam Scatters, Cannons and Missles which won't dent 2+ armour. The flamer template ability is pretty cool when you can move 12" and fire, so if you get a good opportunity you can zoom forward and toast infantry (and again since you only need to clip you can easily damage vehicles at the same time).

It is quite clearly though based around Mobility and ranged fire power seeing as we dont really have access to any heavy hitters in close combat like our craft world brethern or the dark kin.

in my 2k list I running the following (I do'nt remember exactly since I'm at work but this is ballpark)

5x corsair squads with flamer in a falcon with ML and holofields
3x nightspinnners with holofields
3x warphunters with holofields
either prince for bombardment or dream seer with grynx for the reroll.
