Why do you need to replace the adhesive at all? The battery has no room to move inside the phone anyway. It seems the battery is only glued in to discourage DIY replacement.
My method for hardware management during delicate phone surgery is to take and print out on 8.5"x11' paper, one or more pictures of the open phone in various stages of disassembly, and then tape the screws to the appropriate spots on the pictures. Also write numbers on the pictures next the screws to indicate the order in which you removed them.
