I have many questions:

how are the bones set up in a wheeled vehical w/ shocks (front and rear)

how do you make the tires rotate, shocks ... shock, steering wheel turn?

and possibly but not necessary, the pedals move when the gas is pushed and also make the engine parts move?

Don't get me wrong, but you seem to be a beginner modeler and what you're trying to make is more at FragMe!'s level. But who knows maybe you're a fast learner .

So because he seems new he can't try and become better?

I wrote a tut about 9pose, search for that.. That explains everything you want. If you need help with it, post it here

To add to what MandeRek said and to save you some grief.
A vehicle doesn't need bone as such, mostly nulls can be used and it all depends on what you want to do. Even then they are used mostly for weapons.
That being said, shocks don't shock in game, I believe you want the tires to go up and down as you drive along over objects and such, while it may be possible in other games it isn't really possible in BF2.
For wheels turning it is actually the treads that have the texture scrolling across them the wheel doesn't turn. There is a tut in the XSI FAQ about treads.
The good news is the steering wheel can be turned as you steer, as well as having the front wheels steer as well this is done with 9pose animation as mentioned by MandeRek.

My suggestion is start small, get a basic vehicle in game first with working weapons, then move on to adding the extra bits. While they are cool it is mostly the shooting and look of the model that come first.
