Multi-Part skeletal mesh and ragdolls

Hi! First of all, sorry for my very poor english and thanks for your help!

I’m making a character for my game (A human biped), the model is fully rigged and sliced in parts. The probles come when i try to put all this pieces together, im very lost about the correct way of makes the final character and make it compatible with ragdolls. I readed a lot of post etc, but cant find usefull informations. Can somebody help me with that? Im making a medieval game that includes mutilations and i need the character finished for start with the animation process.

Again, sorry for my poor english, but the spanish community is nearly to the dead xD
