After 20 years of rock drumming, I have the following tips for rudiments:

1. Learn to roll - once you  learn one you have them all. You can probably play rock-n-roll without learning to roll properly but you aren't really a drummer until you can roll, kind of thing that separates the gametes from the rest of the germ cells.

2. Hit Flams  - Hey it's fun when you want to make a statement

3. Learn paradiddles FAST. Double-bounce the repeated strokes just like you do in a roll and you can make them wicked fast. Practice them on all the surfaces of the drum set. Play them counter-clockwise with your right hand and clockwise with your left. Play them between your hi-hat and snare. Work them between your feet and hands. They come in very handy in rock and roll.  

4. Learn to play ruffs.

5. Forget the rest unless you're in a drum line. They are still fun to practice but I doubt you'll wish you had memorized rudiment 13 or that anyone will ever ask you play a double-ratamacue ruff drag.
