Paint over polyurethane vs. Strip down to bare wood

Hello everyone, I'm about to embark on a project to refinish my Squier bass and I would like some opinions on this issue. Is it best to remove the polyurethane finish (via heatgun & scraper) and paint from the bare wood, or rough the old finish up with sandpaper then begin painting from there?
 
I should have added that one time I dropped the bass, leaving a small chunk missing from the finish along with some cracks in the area. I have since learned to use strap locks (aka rubber washers). The damage is pictured below:

Does this affect the process at all?
 
All of the above assumes you're going with a solid-color finish. If you want the wood to show through, you'll need to take it down to wood, which is a lot of work.

I am doing a solid color, w/ no intention of having the wood show through.


I repair that kind of damage with CA. It fills in all of the very minor cracks around the main damage nicely, the large,deep area may take 5 - 10 coats to overfil the area. Then block sand down to the proper shape

Sorry, but googling couldn't tell me - what is CA?
