Wow bit of work to do here. You're lacking something big in the army, namely anti-horde firepower. You're going to run into problems against hordes that weave their units together giving both units a cover save, name Orks and Nids, but there are others. Second thing is you completely lack focus in the army. Time to get to work.
HQ- Librarian is a fantastic first choice for
HQ choices. You got his first power right in chosing Null Zone, but the second power needs work. Machine curse is terrible unless you want to shake and stun vehicles to death. Not a good power. Smite isn't bad, but there are better choices. You're better off taking avenger if you want an assault weapon. AP2 just means no
FNP or Termy killing, while Avenger can kill more than four since it auto hits, wounds better since it's a higher Strength, and kills Marines just as well. The other power worth mentioning is Gate of Infinity for objective contesting purposes in the last round of the game, or removing sternguard from trouble. My suggestion is take 2 Librarians with Gate and Null if you're going to run 2 squads of Sternguard.
Elites- First off the Inquisitor... just bad. The psychic hood is normally a good choice, but not on the
LD 8 Inquisitor. That means you have to roll THREE higher than your opponent. If he rolls a 4 you can't beat him, so that's a 50% chance of that wargear doing nothing. Cut the loss and remove the inquisitor since in this list he's a points filler. Moving on to those Sternguard units.. go big or go home. Sternguard work best in 5 and 10 man sizes because of the Combat squads rule. If you're going to use them, make them ten man. If you make them ten man, mount them in a drop pod not a rhino because where the Sternguard really shine is their 5 point combi weapons. The ability to drop them in relatively protected in the drop pod gives you the ability to unleash up to 10 meltagun shots on an unsuspecting enemy tank. Also drop the powerfists since you do not want
SG units locked in combat, use Combat tactics to fail a leadership before combat if possible since you'll regroup and cut them apart with bolter fire.
Troops- Typically you want to try to take only Rhinos or only Razorbacks. If your goal is to sit back and shoot go Razorbacks, if it's to get in close and disgorge a wave of marines go Rhinos. Next Dump the plasma and lascannon squads. You're be better served going with a Flamer/Missile combo because the Lascannons lack anti-horde capability. While a tactical squad should specialize in one thing I.e. Suicide Melta, it should be able to add a second tactical flexibility option. Whether it's being a speed bump in the case of the Suicide melta, or it's taking shots of opportunity at a group of orks. Power fists suck
Tac squads since they do not belong in combat. You have 2 attacks hit once wound once. 25 points for one wound before you get ripped up by combat units isn't worth it.
Fast Attack- Dump the bikers or drop them down to 5 man squads. You're probably better off going with 3 attack bikes instead though, since they have a threat range of 36" (12" movement and 24" melta) and a vehicle danger radius of 24". 110 points less you get an Extra melta, extra range with the melta, but lose 2 wounds. A fair tradeoff in my eyes.
Heavy Support- Dakka preds are a good choice, take 3 instead of 2. Whirlwinds are pretty bad choices since it's True
LoS all they need to see is a piece of the vehicle (Including the weapon) to be able to shoot it. Not to mention for the same points you can increase the front armor by 2 points and have the potential to take out just as many models per turn. Cut the Whirlwind it's just a points vaccuum since it's nothing more than an annoyance to your opponent. In a horde army you're normally fearless (Orks and Nids), or will just Go to Ground so they can get back into the fight (Imperial Guard) and improve their cover save.
Now that I'm done shooting holes in the list I'll offer my take on a better version to the list to go with while keeping most of what you've got in the list into account.

Attach the Librarians to the Sternguard squad. Sternguard drop in taking out high priority/points targets. This means landraiders, or splitting them into combat teams and hitting transports. The Attack bikes hit the heavy support tanks first turn; Hammerheads, Preds, etc. If the Sternguard take wounds to enemy shooting fail the
LD test to fall back and regroup at the end. Use the librarian to gate them away and keep their bolters firing. At this point they won't be seeing the danger the
Tac Squads represent to objectives because the sternguard are being a nuisance to everything on their side of the board.. Remember you only have to take ONE objective more than your opponent to win. This offers you Anti-tank firepower, Anti-horde firepower, and a pair of misdirection units in the Sternguard that can rock your opponents backfield and draw fire away from the tacticals until their set on the objectives and can fire from inside the Rhinos. The reason I upgraded the librarians to Epistolary (I very rarely play them this way) that it allows you to keep coverage of Null zone up while bouncing the Sternguard, or to use their Force weapon if you have no choice. With the 2 psychic hoods you should have more than enough coverage to scare enemy psykers.
