for starters I would like a ultrasonic range sensor and a rotation sensor with a good resoultion (accurate at 6 degrees).
Vexlabs sells a pretty decent ultrasonic range sensor. The way it works is very comparable to Parallax PINGs and other similar brandings, but Vex went out of the way to provide pins for I/O signals. This is very helpful when using a preconfigured control board, like a FRC or Vex controller.

As for a rotation sensor, it depends on what kind of rotation yo are trying to measure. I will assume you would like to sense the rotation of a joint. You should have no problem wiring up a potentiometer or encoder. There's been numerous discussions here on which resistance pot to use and wiring techniques.

Vexlabs sells a 90 ppr encoder. It's non-quadrature, so you'll have to cook up some way to keep track of direction. I'd start off with that and then put those good old problem solving skills to the test. (I mean thats half the fun, isn't it? )
