How much prep work for painting interior walls?

I have a big, big room I'd like to paint. Do I really need to sand and wash every inch of the walls?
I am fairly lazy, but I am a perfectionist. This'll be my first time painting an interior wall of a place that I own (I have painted rental apartments, but never did much prep except for filling nail holes) and I want to do it right. However, I have a LOT of area to cover. It's my entire downstairs, and the "room" measures something like 25 by 40 feet. From what I've read, to paint a room right you need to sand the entire wall, wash it with some mild detergent solution (or even just water to get the dust off), before painting. How necessary is this step? Could I get away with simply washing any smudges and doing hole-patching and sanding -- basically, spot-work? Or would I end up with some bad-looking walls?
