Learning Shorthanded Play

[THWAP!]

I have vague aspirations of playing higher games. And there have been a bunch of those types of hands posted lately. There, you tend to have to do more shorthanded playing. Like, heads up and three handed. And if you aren't willing to play shorthanded, game selection is more difficult.

So, I have two questions:

(1) (very broadly) what should you do differently when playing shorthanded? I realize this is broad. I'm trying to get more specific advice than "be more aggressive." I'm just not sure where to begin. Sorry this was vague.

(2) (thankfully, a more specific question). How should I go about learning SH play? I mean, I could play 6 max-type games. But I'm not sure how good of preparation they are. So, specific suggestions (such as "sit alone at a $25 NL table and just take on all comers for the next week") are welcome. though maybe not as tongue-in-cheek as that example.
