I dabble in paint, been doing it a couple years now. Your plan is running in the right direction. Only bare materials need a primer, but I suggest priming the entire surface. After you let the primer dry, take a look at the piece from all angles and if there are any imperfections then the primer will bring them to sight. This way you don't spray color on your part just to find out you have a pin hole or some other imperfection. If you find a flaw that you cannot live with, wet sand the primer and spray again. If it's a deep flaw then you need to use some Bondo spot puddy, let dry, wet sand smooth, prime again, inspect, repeat if necessary.
Certain flaws in spots that aren't easily noticeable I wouldn't go through the trouble of making perfect, but of course that's all up to you. For large flaws after fiberglass or plastic weld repairs I recommend Bondo short strand fiberglass body filler. It's a two part product (add hardener) with fiberglass hair already in it. You mix it up and spread it on with a grocery store plastic card (well that's what I used since they're free, flexible, and work perfectly). Just make sure you add the correct amount of hardener; too little and the shit will take forever (like a day) to dry, or too much and it'll dry before you get a chance to spread it on evenly. I like to add a little more than recommended since it takes a quick mix, scoop up with the card, then slap it on the part. It'll dry enough for sanding in like 20 minutes or so. Great stuff.
Hope that helps.
