how deep are the scratches? if they are just light scratches (fingernail scratches by your door handle) and not down to bare metal or primer you could try to wet sand them first to see if you can totally avoid repainting. For deeper scratches try using 100 grit on a DA to get the majority of the scratch out. then just go over it with 220 to feather out the area around it. hit it with primer and block sand it down and you should be ready for paint.

unless you are doing a complete paint job, you don't have to take it down to bare metal. Just make sure that you paint an entire panel (ie. entire door, bedside, hood etc). You will likely run into flaking and peeling paint if you try to "blend" new paint into old by only painting a portion of the panel. not to mention it is a lot harder to match the color of older paint that way.
