There are great threads on each of your areas of concern, so for the most thorough answers, I'd recommend you use the Search function.
In brief, here's my $.02:
-depending on the scratches (how light, etc) you can use
DACP, then something lighter to get out any haze. I do this with a PC and a yellow pad. If they are more severe you may need to use a rotary, but don't do this unless you know what you are doing.
-Drying: Try the big blue MF waffle weave towel from CMA.
But again, read up through the Search function and you'll get more thorough information.
