You seem to be doing fine and you have gotten a lot of good advice.
It's a plus that you are going to use bulkhead fittings and not just trying to seal it with a bunch of goop. Bulkhead fittings are the ultimate best way to a positive seal.
Dont worry.
When drilling the plastic, go slow. Too much speed will cause the bit to melt the plastic. The bit can get stuck and if it heats up too much, the hole can become distorted. Go real slow. Cut through the plastic, don't melt through it. You want a clean smooth finish so your bulkhead can properly seal. Drill a little at low speed. Stop and let it cool then repeat. Again, cut through it, not melt through it.
I don't know what the glass cutter you are talking about is, but I have used hole saws for 45 years on all different materials. As long as the hole saw is sharp, you are good. If it's dull, it won't cut, it will melt.
