I'm working on an A-10 Thunderbolt right now, Artimise and I have built quite a few.
Robots gave you a good tip.
I suspect you have enough artistic talent to jump right in.
It's a long process but very rewarding when you get there. The first thing I would suggest is that you can't do it without an airbrush so get an "okay one" and start there. Harbor freight has a good deal on a compressor/airbrush combo right now. I did the air cans for a while and ended paying so much in cans that I could have bought a really nice airbrush before I finished my first model. I'd start with Tamiya acrylic model paint and not oils, like Testors, the acrylic is easier to clean up, you won't have to paint outside for fear of killing the family with the fumes, and the stuff goes on so smooth.
I paint everything on the sprue, including my dry-brushing for weathering the cockpit and other pieces then I put it all together. I paint the fuselage and wings with a base color first then I glue the whole thing together. I then coat it with a gloss clear coat, let it dry very well. Make a wash by watering down black paint then use a brush and paint it in all the panel seams and details. Quickly take a wet towel and wipe all of it off while wiping front to back and then you have nice panel details.
Another method is to paint everything black then do your top colors but airbrush over all the seams lightly so the black shows through slightly.
There are a lot of methods and a lot of cool little tricks so let me know if you need any help.
