Sorry for the 2nd replay to this thread, I couldn't remember the URL to something before.
Detailed Image, a retailer of many different brands of products has done some nice write ups and articles on how to detail your car. I know a lot of us have been talking about what to use, but if your not experienced with the HOW or Why, the What to use is irrelevant. You can have the 'best products in the world' but if you don't know what your doing, your never going to get a good result. I am not trying to promote the company or saying you should buy from them, just offering some of their videos and articles as information. I do order some of my products from them in part because they are not all that far from me so shipping / delivery times are relatively good and prices are okay.
Anyhow take a look at their detailing guide. I think it will help you in determining what you need.

Oh, one last thought... If your going to get into using a rotary buffer and compounding or paint correction kind of tasks and you have never done anything like it, see if there is a junk yard near by or a body shop that will sell you some slightly damaged body panels (some body shops will give them to you free) to practice on. I have seen people using aggressive compounds or high speed rotary buffers (not DA buffers though it can be done) do some nasty damage to their car. It will allow you to get a feel for how to do some of the tasks without the worry of messing up your new baby as well as giving you an idea of how a product preforms and can be compared to others because who cares if the junk panel has 3 -5 different kinds of wax, polish, glaze..... on it
