Recommended Rigging Technique?

Basically, I want to create an animation style similar to Family Guy’s. How would I go about rigging a character the way they do? Should I have a separate rig for each pose? A Separate rig for clothes? Should I split my arms into two parts? (Actually, any advice on rigging arms would be great, especially switching between having them in front and behind the body)

I don’t want to do everything like them but their characters are really well done so how would you go about rigging a character similar to theirs?
