Yes, you should see a spark across the points with the cap off.

Easiest way to check the cap/rotor is to set your meter to ohms. Put one lead in the coil whole and one in a cylinder hole. Crank or turn the engine and watch the reading go to "no resistance" as the rotor contacts the lug inside the cap.

Gas to the carb is a good sign, but you should still check for a squirt from the accelerator pump.
