Thanks Cyorysh, any suggestions are appreciated

I just started playing, so any advice or criticism is welcome. I have been trying to rework my list, this is what I have so far;
HQ
Librarian
Terminator Armor, Epistolary
Elites
Dreadnought - 160
Heavy Flamer, Autocannon, Drop Pod
Ironclad Dreadnought - 185
Assault Launchers, Drop pod
Terminator Assault Squad - 200
TH/
SS
Troops
Tactical Squad - 210
Multi-Melta, Meltagun, Rhino
Tactical Squad - 205
Flamer, Heavy Bolter, Rhino
Scout Sniper Squad - 105
Camo Cloaks x5, Teleport Homer
Heavy Support
Vindicator - 115
1360/1500
I am not sure on what to add for Fast Attack or Heavy Support. I'm tempted to do a Devastator Squad w/ Razorback, but I don't know how that will fare. I have two weeks to finish up painting, so buying new minis might not be an option either.
Edit: also, what should I take psychic power wise for the Librarian? I'm wanting to play him in a support role mostly.
