If I'm not able to get off all the existing rust, will this still inhibit it from spreading?

I would use Rust-Oleum RUSTY METAL PRIMER SPRAY instead. It transforms heavily-rusted metal into a paintable surface It bonds tightly to rust and forms a surface top coats can adhere to—while driving out the corrosive air and moisture other primers leave behind.

does this work on wood?

Yes, but it is fairly thin and designed for a hard finish like metal or fiberglass. A thicker primer designed for wood would work better.

This is a primer. So after applying it on my car panel, I still need to apply my choice of top coat finish. Correct?

Apply primer, sand, apply primer, sand then paint then clear coat
