OP also that kit on Amazon is a pretty decent starter pack. I like Meg's...I use some other products though as well, but their waxes/polishes and tire care are my go to's.
For interior upholstery/carpets: Detailers Paradise/DP
For plastic protection and cleaning: 303 cleaner and 303 protectant
For Leather: Tanner's Preserve, Lexol, and Leatherique for major overhauls and long term maintenance.
I'd join Autopia.com and meguiarsonline.com
Autogeek.net is a great site for products.
If you plan on keeping up with your car, 128oz concentrates and products are a great value. This is a list of my orders from them over the last 4 years:

If you have excellent water pressure and are 'gentle', the $19.99 fireman nozzle above is nice.
The Clayworks pad for a machine polisher was not worth it, do your claying by hand.
The Detailer's Paradise Carpet Extractor Pre-Treatment requires a HOT WATER extractor. Also it didn't provide much of a difference than Folex (at Home Depot) and DP's normal carpet cleaner.
Red Bufferstick Wheel Polishing Tool, I never used. It was a product I didn't fully trust over doing it by hand.
303 Fabric Guard I worried about affecting the upholstery esp. seating surfaces. If I had kids I'd give it a go, but I am pretty clean when I drive and if I am dirty I throw on a seat protector or towel first.
I like the Shampoo Plus car wash...Hyper Wash is more economical, but not as lubricating.
Meguiar's 135 Detailing Spray is much like Ultimate Quick Detailer to me. Last Touch is more lubricating for dirty days and works great with a 1:1 water mix for a clay lube.
All the Cobra Microfiber products are great bang for bucks. The 'yellows' are my disposables.
A lot of the Wave pads I bought I rarely use. The red, white and blue are pretty much all I have needed.
I really like the Clay Magic Red and Blue product line. There was a shop that had comparable products in bulk much cheaper, but they no longer sell it.
I bought my Porter Cable 7424 for $99 with the 7336's 6" counter weight and a hook and look backing plate from CoastalTool. They don't show up on many 'shopping searches'. They are offering the 7424XP for $125 now in the same deal.

I also like the "Absorber" product for drying. You have to be careful with it though as there is no buffer if you pick up something that can scratch.
