Don't bother. A few little rust holes won't make any difference at all in performance.

Also, how good a job do I have to do with sanding the rust off? If I half ass it can I expect the rustoleum to still keep the rust in check?

Angle grinder and wire wheel.

If I rustoleum over the holes Am I done and done? Or will the rusties spread?

It will eventually spread, unless the rust has been COMPLETELY removed (by grinding, cutting, etc)- which paint will not do. It's hardly different than having a water leak instead a wall of your bathroom - painting the wall won't solve the problem.
