Definitely work on your short game.
The short game accounts for more strokes than any other part of your game. If you take a look at an average breakdown of a round for someone who shoots a 100, it's probably something like this:
Putts: 38
Chip-100yds: 25
100-200yds: 20
200+ yds: 17
Between 100yds out and your putting, you have the two areas where you can shave the most strokes from your round.
Most guys just want to go out and hit the long ball (myself included), but if you really want to cut strokes from your game, work on your 100yds-and-in game first... THAT'S where you'll see the biggest difference.
