If you have a red 2-pin connector like those on GWS ESC's, then connect the battery to the 2-pin red connector, the motor to the 2-pin black connector, and the other end goes into the speed control plug on the reciver.
With the EPS-100 (which is a better motor, from what I have heard, for the slowstick) you need a 5 amp ESC. The EPS-100 should have at least a 7 amp ESC. The Pixie-7 is the best for the the EPS-100, and the EPS-300 works great with the Pixie-10 or higher. The E-tec 1200's might have some trouble with the EPS-300, so try some High Discharge Kokam 1500's (35.00 a pack). They are only a few grams more, and can take up to speed 400's. The AAA's you are using should be fine for both motors, although you may as well go LiPoly, as the flight times are well worth the extra cost.
A word of advice:
NEVER, EVER, EVER use Li-Pos with a GWS ESC. They will wreck the batteries if you are not constantly checking the voltage. You will save money in the long run by getting a Castle Creations ESC, partially because they are lighter, have nmore features, and are more durable than the GWS crap. 2 GWS ICS-100's are more expensive than one Pixie 7, and the Pixie can take 50% more amperage.
