Meguires is pretty simple to use as you say, and it gives great results
I've been using the Gold Class wash and waxes for the last couple of years, but a fair few people have started saying the NXT stuff they do is great and gives a real deepness to the colour of their MINI's, so I am making a swap over to that later this week
The lambs wool wash mitt is great, but don't use it on your hood, as it will look like you have had a dozen cats sleeping on it
The wax application pads and polishing cloth make waxing such an easy job, so really recommend you get those
Other brands that are popular are autoglym or zymol, and again give good results
Infact I use the autoglym artifical leather, and the trim cleaning gel, as those are hard to beat.
Main thing to do is to make sure you don't take it to a auto washing machine, those destroy your car and its paint work
