As Ali said a lot of it is down to trying the products and seeing whats right for you. You have a good selection of products there. It might be worth dropping TK Tom a quick email and asking him. He detailed my JCW and I picked up some great tips off of him. Mine will be going back to him in the Spring to be fully detailed and have a ceramic finish put on it, which my company will be filming.
Don't take it as law but in my opinion to put a small detailing kit together you'll need something like:
1: a cleanse for pre wash. I currently use Waxtec citrus cleanse, which I buy in concentrated form and dilute to a consistency that I need depending on how dirty the car it.
2: A fallout product of some sort. Loads on the market but I use Britemax grimeout for the wheels .Again you can use this neat or dilute it to suit the needs of what your are doing. Cant remember the name of the Fallout stuff.
3: Snow foam - I use Autobrite
4: PH neutral shampoo
5: A Sealant. I use Waxtec, if find this a nice product to use, as it removes any streaks that you have have missed and great if you want to put a nice shine on the car without spending the time of polishing and waxing.
6: A decent polish. I use Britemax Blackmax. Great product and easy to use. It can also be used as a paint cleanse before you wax.
7. The best wax that you can afford. I both have Britemax (£40ish) and Swissvax(Well over £100)
I do have lots (and I mean lots) of other products that I use, but i'm beginning to bore myself whilst writing this. So if you need any help/advice, you can PM me and I'll be happy answer any questions.
Good luck and happy detailing
