: I did a precoat on the hull last night. The surface of the hull is pretty
: bumpy in some areas now, as you can see in the photo below. Should I go
: over the surface lightly with 120 grit to knock down the bumps a bit? Or
: maybe it doesn't matter too much once the glass is on top?

I knock off the highs with a cabinet scraper. It takes all of ten minutes to do. The only reason is it to keep the cloth from snagging so it drapes better.

Do not sand. If you sand too deep, the wood color lightens and does not rewet with the next epoxy coat and will not darken to match.
