With the weapons, I would use foam for all of it. No pep wrok. With weapons, such as an M6C/SOCOM (M6S), pep can easily get far too fiddly. As for the gloves, good idea making them out of paper first. If you do the gloves so that they are similar to in Halo 3/Reach, you could get away with some ski gloves, or something similar.
