The nomex glues would be fine. That's what I use. For cutting if you can get your hands on an exacto knife that works the best for me. The score and snap method works the best for me. I used it on some of my stormtrooper suit and did nothing but that method on the clone that I am currently working on. Can you get your hands on a rivet gun? If you can, you can get that sniper knee plate on in a few minutes. No worries about the belt mate, we'll help you out as much as well can with your armor adventures. I wish I had found this place before I bought my first set of armor and assembled it, it would have saved me a lot of extra work.
