I've always been a little obsessive about taking care of my cars, so you may not want to go as extreme, but the service manager did mention mine was one of the cleanest they'd had in for yearly service ;-).
Griot's Garage has a detailing handbook that is a great place to start. When I got my used 911, I did the whole treatment, top to bottom, and it looked a bunch better - not quite new, but close. With a new car, things are much easier - the paint is still clean and doesn't need to have the fine scratches buffed out.
Do not use just any cloth/rag on your car! They will scratch the clear coat! Not in an obvious way, so I'm sure there are many people out there who will say "it doesn't matter" - but at certain angles... Good microfiber or pure cotton towels are recommended. A good boar's hair brush to help gently clean the exterior is good. A small detail brush (thing old-timey shaving cream brush) is good for interior detailing - getting the dust out of the corners.
As for product line,
Zaino. No question -
especially if you have the paint armor. Wax will just emphasize the paint armor instead of making it less obvious. Zaino's product line doesn't cover everything you need, so you need to fill in - I usually fill in from Griot's line.
For the soft top, RagTopp makes a cleaner / protector pair. It's what comes with a lot of soft tops.
For the interior, I use Griot's leather wipes at least once a month on the seats and leather parts, interior cleaner on the rest. Except for the carbon fiber or exposed paint parts, which I treat like exterior.
I've got the black wheels - I treat them like I treat the paint.
I agree on the California Duster - I have two, a big one for the body and a small one for the wheels (which gets dirtier faster). Also, whatever product line you choose, they usually have an 'in-between' wash quick-detail spray something or other to apply after dusting between washes.
I've got a picture from the March road rally - where I spent the entire previous day taking care of the car - which justifies (IMO) the time I spent.
Plus, the car just drives better when it's that clean.
