Painting a repainted car?

My car was repainted before I got it. I am almost finished with all the mechanical work. Originally, it was going to be a street/strip car and I was ok with the paint. Now that our drag strip has closed, I am going to make it a driver. I want to redo the paint but have never painted before. One side the panels are nice and straight but the passenger side has seen obvious repairs before. I do not plan on making it a show car but I want it to look good.

There is not any visible rust anywhere. Where do I start to assess the damage, learn about prep and paint techniques? I like the color but I am open to change. I know that many others have done this before me. Help me follow in your footsteps. I like to study techniques so books, youtube or websites appreciated.View attachment 1715719839
Love the color it is but if it was me seeing that side of the car I would strip it to bare metal and redo the body work so it was straight and make sure no rust has been filled in with just bondo and paint. You never know how much it will cost till you get it to bare metal and see what is hidden behind the paint and bondo.
Lots of guys here to help and really depends on how much you want to spend on getting it fixed right.
