750pts is a low limit for Eldar, try and convince people to play higher pt games
As for your list:
Farseer is a solid choice, but Fortune and the Spirit Stones could be dropped. There simply isn't many units that would gain much from re-rolling armor in your list. The
WL is the most likely target, but guns hitting him will probably the standard anti-tank weapons (since you have no tanks), which ignore his armor anyway. And, the Farseer himself isn't really worth keeping the Fortune on.
Harlies can be a really good choice. Drop the Death Jester (he's the one with the Shrieker Cannon, right? If not, drop the one that has that). You'll be running or assaulting every turn with these guys, they can go an entire game without shooting once, and the Jester becomes more of a liability than an advantage.
Pathfinders are good. Be careful with them, though. You'll have to deploy them on objectives often times outside your deployment zone, and without transports in your army to bring in backup, they get assaulted pretty quickly and wiped out.
The Wraithlord is an interesting choice. He's your only ranged anti-vehicle in the army, so you need to use him for that as much as you can before he goes down. I like the weapon loadout on him, but remember without a sword he actually isn't very impressive in
CC.
Overall, I think this list is kinda iffy. Tanks and Mech armies will chew you up pretty easily, but at 750pts, you may not see many of those armies.
KP games are going to be your best bet, but I guess objective games to be almost unwinnable if your opponent can close distances quickly. You may want to try a Jetbike squad (or Dire Avengers in a
WS) held back in reserves to quickly capture that critical objective turn 5.
