After a bit of reading on the site, I have came up with many solutions to my problems.
1: The elbow and shoulder pads will not be fixed to existing pads but rather will be padded with a dark color foam (if such a thing exists) or have the foam covered in a dark fabric that is thin and in between the elbow and shoulder pads will be a velcro strap and a loop so it can fit snugly to the arms/ elbow. The same will go for the knees and shins.
2: I will follow the advice of the forums to use the not so sharp side of an x-acto and a metal ruler to help score the folds. This should solve the gad headache as seen on my tests.
3: Since the insides will be padded, I think I can get away with normal but military colored clothing.
4: I found my black boots that still fit me. All though they are not military style, I will still fabricate armor for them. Design to follow.
5: I have found on ebay flat top rimmed shooting glasses. This will be great for my helmet as all I have to do is cut the arms off and glue the rest onto the helmet.
6: As for the mouth piece, I always have one for my cell phone and always wear it when I'm out. Plus, I used medical tape to reconnect some split wires so points for battlefield repairs. Before anyone freaks out, my dad is an automotive mechanic and model railroader, we do this all the time with various other tapes; just the medical was closest to me at the time.
7: I have not decided if I shall have a new, straight from the factory look or a rough, battle worn look to my armor. I'll see after the first coat of bondo goes on.
Well, that's that guys and gals. I'll update you all if anything significant happens. Oh yeah, before I go. My printer printed on the 65 lb paper blue, not black. Could be an ink problem or something else.
