You seem to be on the right track for a light to medium correction. The white pad is pretty light so I generally recommend the Lake Country Green / Pink Very Light Cutting Pad
but a white pad will work. It's a close call that depends on the vehicle and personal preference. I'm also a much bigger fan of the flat pads instead of CCS but to each their own.
For speeds generally you'll want to polish at speeds 4 - 6, glazes and AIO's 3 - 4, sealants and liquid waxes 2 - 4. If you are new to the buffer start at slower speeds until you feel more comfortable.
For tips on how to polish, use the buffer, etc. check out our detailing guide
and our Ask a Pro Detailer Blog
. Good luck!
