Since you are doing it ALL by hand I would just clay, then get a good cleaner wax. That way you will really see what you are up against.
Honestly, getting set up to detail properly will cost a few $$. Start slow and build your arsenal.
A DA polisher,proper pads and backing plate, the 'right' kind of microfibers(so you don't destroy your work), compounds, polishes and your choice of sealant would be a start.
Meguiars line is definitely user friendly. Ultimate compound, ultimate polish and ultimate wax(the 3Us) will do a 180 on your car.
If you can catch a fingernail in a scratch, it won't buff out.
Time to browse Meguiars online and AutoGeek my friend.
