What is the amp rating per screw?

About 15amp but should handle up to 25amp could be more depending on your wires awg

100a or 150a for a boat?

All depends on what your hooking up. Normally 100 Amp is plenty. And this is a grounding strip. If you have a large load -Spot Lights, Down riggers, bilge pumps, Stereo, 2-way radio etc, etc you'll have to do the math. But since your buying a grounding lug this should have already been done on your fused feeders.

What size ring terminals would I need to get for the screw and stud connections.

I measured the post and screw. The main posts on either end are for 1/4" ring terminals and the screws are for #8 ring terminals.

Where can I buy a cover for this bus bar?

Try going direct to the manufacture. Amazon has the item listed with & without the cover, but they do not list the over as a separate order-able item.
