Newbie Wolf/General questions

Hey, I'm slowly working through my PS2 collection, and I've begun playing VF4:E. I'm digging me some Wolf H, and I wanted to ask some questions:

-I get floated. A lot. And it hurts. Is there any way to fight out of a floating combo?

-What is the use/significance of Reject Wall? I've drilled a little with it in Training, but I don't know a lot about bringing it to a fight. Does it cover highs, mids, and lows? How generous is the window to use it? What do y'all like to chain with it?

-Can any of the ground grapples/pick-up be much use gainst the CPU, or are they limited to guys who lay down forever?

-What are the best one-strike, quick-strike, and combo moves to learn?

-Do you find it easy or hard to incorporate Wolf's command throws? I get kinda spazzy and double-tap directions more than I ought. I also find the half-circle/quarter-circle moves hit-and-miss on the PS2 pad.

-Do you develop decent combo recognition against the CPU? I don't like blocking, but when I whiff a block, man, it makes me pay.

That's what I have right now. The game is a lot of fun, but it forces me to be a lot more disciplined than I have ever been before for a fighting/wrestling/action game.
