Not to burst your bubble, but you are talking about the Eldar codex. Short of putting down all Guardians in their skivies, pretty much anything you play will be called Cheese. That said, the list looks like a good starting point and if that is what you want to play, do it.
The Warlock cannot join anyone, though an IC can join the Warlock since he is not a Character. I like the way you're outfitting your bikes and agree about the Cannons over Lasers. I wonder if you could drop the S Cannons on the Wraithknight and fit in another Bike?
