Glue is upto you. Remember you are going to glue ontop of either true fiberglass fuse or a wood fuse that you fiberglass yourself so its going to be a smooth paintable surface.

Most folks I've seen use elmers white glue. Also you can use flat brass for your template. Simply drill evenly spaced holes in it and line it up on the panel line. It can be used for both the flush or raised rivet. Just remember that rivets on planes are not uniform. They are not always perfectly straight either.

As for the Zero....Not sure. It may be like many US planes where it changed depending on the model and year it was built. Just do a google image search of the specific version you are looking for.
