Can I use foam AND cardstock to make the armor?  Could I make the outside cardstock and the inner layer out of foam as to give it some bulk?  
Also, once I trace and cut out my foam pieces, how exactly do I glue them together? From what I understand, I'm supposed to cut out a small section on the connecting side of a piece which is about half of the total depth of the piece, and do the inverse on the corresponding piece. After this I glue the two half cuts together to make a piece with full thickness. Am I completely off base with this?
Thanks for the help all!
