Step 11 says not to insert your pick around the right side to avoid damaging cables, then Step 12 says to insert it on the right side. Help, I'm confused!

I'm wondering about putting it back together. Different wires and small parts etc were glued or adhered in some way to the case or sides or whatever, as it is put together in the beginning. Is that just to make it easier to put it back together? Should I try to stick them back the way they were with something? Can you use tape or glue if it's just a wire? I wouldn't want to use something that would melt...or is this not something to worry apout?
