Sorry, I haven't been on here to give you any tips from the way I do things. I have worked at a few body shops and they all do things differently. Some only swear by their way, but I can tell you that a good paint job is mostly in the prep work and that is where you should spend most of your time.
Now I will probably forget some of the questions that you asked so if you have any just send me an email at

To fix kits I use the fiberglass resin and cloth. I cut the cloth the shape and length I need for the repair. I usually do few layers to give it some more strength. I mix the resin by the instructions into a small plastic bowl that is flexible so that I can pop the hardened stuff out of the bowl to reuse it later. I apply the resin with a paint brush, size depending on the size of the job. It helps if you apply resin to the part first, then lay a piece of cloth down, and then saturate it with resin pushing any kind of bubbles out with the brush. Use a like a dabbing motion and not a painting one because you will just pull apart the cloth. Also to go around tight corners pull the cloth apart and kind of fray it.
You could also use the tiger hair or kitty hair that you got, the fiberglass reinforced plastic filler; but it will be harder to repair the next time if it cracks again. I have repaired kits that have hit walls at 80mph and blown off into three pieces.
http://youtube.com/watch?v=qlIT8_H0X9cI repaired the kit on the orange Sil80, that was also painted by me. The rear shot off into like three or four pieces and I was able to save the bottom section. I riveted that onto a stock bumper to get a cool ground effects thing. The side skirt also broke into two pieces; that turned out so good you can't even tell it was in a wreck that bad.
One major thing that I want to tell you is screw that one part glazing putty ****. That stuff is pure junk. Get the Bondo two part glazing putty that uses the same catalyst as your normal plastic filler. Also don't use crappy primer out of a spray bomb, I just tried this on a bike tank I just finished this week. I had just some small sections where metal was showing through after I wet sanded it that I wanted to get sealed up. So I spray painted them and wet sanded it again. When I went to go us the wax and grease remover before I painted them I noticed there was a bare spot. Then I realized that the wax and grease ate the spray bomb primer off and I just wasted nearly a hour on a try at a quck fix that ended up not even being worth doing.
On prepping the car for for primer I and sanding filler this is how I do it. I usually only use 32/40 when something is really f-ed up and I need to cover nearly a whole panel. Other than that I use 80 or close to it for sanding filler. I grab an old piece to take of the paraffin layer that always clogs up the sand paper. Then I DA, dual action, sand the whole car down with 120 or you can do that by hand. After you prime it put a guide coat down, which is just a mist coat down of some flat black. This really allows to see your low spots that need more sanding and such.
Umm, I have to cut this short so if you have any more question just send me an email or ask them on here.
