1) Olsen's book is alright, but don't knock yourself out trying to find it. It's a good read for fans, but as far as solid references on the layout of the various colors, it lacks the sort of information modelers demand.
2) Aztec Dummy's 1/350 set is sort of hit or miss. They lay smoothly, but the vinyl material is a bit thick and the adhesive is fairly aggressive. A good alternative is the set from Orbital Drydock. The material is substantially thinner, the adhesive removes easily, and the set is a little more detailed and comprehensive.
3) I went with Tamiya white primer, then sealed with Tamiya's pearlescent clear. No compatibility problems and the Tamiya offers a better finish than the Testers in my experiments.
4) Careful with the Polytranspar - this stuff is an incredibly potent lacquer that gives off a very strong smell that lingers for days if not vented properly. It's not exactly cheap, either. The shimmer effect is great, but you'll need to experiment with the paints first because the blues and greens can go from slightly transparent to patently opaque if you don't mix and thin them properly. Lacquer runs hot, so be careful to go with light coats through the airbrush.
An alternative there is the parliament powders available in art supply departments of stores like Michael's and Hobby Lobby. Mix a small amount of the powder in with a clear gloss (I know a few guys who have used Future) until you reach your desired level of opacity. It's a little more forgiving and there are a lot less fumes to deal with.
Above all, keep it subtle - it's very easy to go overboard with the colors and you wind up with a brightly colored Easter Egg, rather than a Federation starship. In any event, Aztecing requires a large degree of experimentation, expense, and a bit of practice, in addition to a lot of labor hours. It's a lot to get right straight from the start, but the results can be stunning.
