I'm totally new to bullet (or any other physics engine), but it seems quite amazing and useful.

Sorry for my noob questions and errors I may say during this post (even in what concerns english errors).

So when i found out about this physics engine I realize that it was the "Holy Grail" for solving my project problem. I want to create a simulation game where a few objects can interacte with each others obeying physics and real laws. I was thinking in use XNA 4.0 to make my game (i already have the 3D models i want and know how to import them) and is a tool i'm now some kind of used to.
I read in homepage that this engine is integrated in blender. I already study that and start seeing how blender works and use some of the tools of bullet in there. One more time I realize this was an amazing tool for my project. But then one question came to my mind: if i made a model (or change the ones i have) with bullet in blender (to make them soft bodys, or rigid bodys or whatever) when i import them to XNA they will have their properties? But even so, how do i integrate the physics librarie so they can interacte (collide, one grab other, or some other real stuff)?
I kind want to know if i can even use Bullet in XNA (if yes, how i do it (is there any tutorial?), if no what do you advice me to make my simulation?), can i make my model more realistic with blender using physics engine there and then use them in XNA (or this kind of properties is completely configurable in XNA with bullet librarie?).
I think you understand what i want, i'm hoping someone can tell me what can be done nowadays with this engine and how can i do it. I understand is too many questions and maybe noob ones, but i hope someone can help me out.
Thx in advance.

Best regards,
