I think any of the Dodo juice wax's would be good but I have a blue car and I use the purple haze soft wax and it is realy good and very easy to use. Regarding a claying routine, I wash and then clay my car and if you've never used clay before you could try the Megs or Autoglym clay kits which will provide you with everything you need and a resonable end result or you could try Bilt-Hamber Auto clay as it only requires water for lube making it very cost effective and it is a very good clay (There are lots of other types of clay you could use). After claying I would rinse or re-wash the car and then apply my chosen polish which would be followed by a sealer and then a wax but if your pressed for time you could just apply a polish then the wax or the polish and then the sealer, applying the wax at a later date after once again re-washing the car.
This is a decent guide to claying http://www.youtube.com/watch?v=yfEfLGL59GI
