#1 Yes some are made this way....just heavy fiberglass, may have have cardboard or somthing at one time but long since gone.

#2 Yes I would use a layer of 1.5 oz CSM and polyester resin between the layers of plywood and 2 or three layers (depending on how flat and smooth it is) between the skin (outside hull) and the plywood.

#3 I've seen both ways....an aluminum cap riveted or screwed is the most common.

Re: transom replacement

Not familiar with your particular boat, but it's possible the hull and cap were 'tabbed' together, which is when you have a small section of fiberglass connecting two pieces like you describe.

And you lucked out not having to worry about stringers to repair!

2) I laminated my transom together using epoxy only. You would get the simialr strength using poly and csm. I'm going to wrap mine with 2 layers of csm and poly resin when done. My link below shows what I'm doin'.
