Just a few simple answers from me, though cricket hits them all as well. Return edge is not required anywhere on your kit. Though there are the two places it is a must to remove them, wrist side of the forearm and the bottom of the shins. However no return edge is required to stay. Most people trim theirs to roughly 3-5mm. Plus most screen used costumes had little to none on them. Snaps plates can be any thing and a personal choice. Though nylon webbing I think is become the more popular choice for them. Suspenders vs. garter. Again a personal choice I think most people use the garter system though.
