Everyone has such radically different needs and different learning styles that there's no "right" answer here. Having said that, there's a few ideas:
If money is no object, you should probably start by signing up for a Kaplan class since that will immediately give you a huge raft of resources and (unless they've changed since I left) Kaplan is the only classroom company that will let you do infinite "teacher shopping" - so you can hop around between different classes / online classes until you find a teacher you really click with.
Then you could think about getting one-on-one help, if you're the kind of person that works well in that environment. The key recommendation I'd make here is to use two different companies for your classroom and one-on-one help (e.g. TPR class / KTP tutoring; EK class / NS tutoring; KTP class / EK tutoring, etc.) so that you can get different perspectives on the new test. Since no one company is going to have the perfect "take" on the new test, you want a variety of perspectives.
For books, again the main thing I'd recommend if you can just buy all of them would be to put together a set of books that's a mix-match from different companies, to spread the risk around, so to speak. So like the KTP Biochem, the TPR Pysch, the EK Chem/Physics, etc.
Finally, take the "diversified portfolio" approach to your tests as well. EK, NS, GS, TPR all sell tests as separate products. So if you take a KTP class to get their tests, you buy the AAMC tests, and then buy tests from 1-3 other companies, and make sure you create a once-a-week schedule where you don't do more than like 1-2 tests from each company, you'll be sure to get the widest possible range of practice.
You're in a really enviable position. The absolute key thing here is that after you've put together your suite of materials DO NOT KEEP SKIPPING AROUND. With access to that much stuff it will be easy to lose focus. Set up a set of materials, develop a study schedule and then GIVE AWAY everything you're not using. It will just distract you. Stay focused, keep moving.
Good luck!!
