I just threw this together to help show what is what:
I've only done the front right now. The names are the same as my unfolded files.
What I'd suggest you (anyone building the armor) do is to build all the pep pieces and possibly fiberglass (or whatever you're going to do to strengthen it) it all before you start doing any major work on it, that way you'll give those working on the drawings and other details enough time to work on it at a comfortable pace and they wont have to worry about people asking questions that they don't have answers to yet
As for any general questions about construction, feel free to post here, in my ODST thread (which I'm working on right now) or if you have to, PM me (I'm a bit behind on replying to PM's though)... I've got almost all the pieces cut and ready for folding and I'll try to help where possible
