Stay Awhile, and Listen! - GK units to use?

As you all know, I'm starting up GK as my second army - I want to run a terminator list, not necessarily Draigowing, but might include paladins. My question for you all is this - If you had to pick some auto includes for a termy list, what would you say they are? I.E., opinions on Justicar Thawn? What psychic powers on Libbies would you say are most useful? I was looking at Sanctuary, Warp Quake, The Shrouding, and Might of Titan. Quicksilver is also a possibility - has anyone gotten good use out of it?

My current list is this, but it's really just theoryhammer. Please post opinions on it! I want it to be fine tuned before I start buying bunches of models. The theory behind it is to put two squads of termies with the GM and Libby in the ravens, then give the ravens scout and get the first turn assault with termies. The third squad will sit in deep strike and drop down where support is needed, which is pretty well controlled with the GM's psychic communion. The Dreadknight will either outflank with Scout from Grand Strategy (if I roll high enough on the D3) or just jump up behind the ravens and drop flame all over the place then shunt wherever he's needed most. Alternatively, he can be held in reserve with the other termy squad to supply reinforcements where needed. I'm thinking of dropping the Dreadknight for 2 Psyflemen, though - thoughts?
