Rob, I'm not really sure what you're asking with the latter part, but rigging eyes is relatively easy.
There are multiple ways of doing it, but a simple way is to position left eye and right eye bones starting from the center of the sphere and extending out through where the pupils are. Assign the CPs for each eye to the correct bone and then add a third bone in the center between the eyes. This will be your control bone. Create a new On/Off pose and edit the pose. You want to apply offset constraints to the two eye bones so that they will orient like the control bone. Once you've done this, you can hide the eye bones and making sure the new pose is turned on, you'll be able to control the eyes with one bone.
Alternately, you can create a Null and use aim at constraints so that the eyes will always point at the null. Then wherever you move the Null, your eyes will follow.
Look for some of the basic rigging tutorials to learn about the basic principles of rigging. There are some amazingly complex rigs out there, but basic rigging in A:M is really, really easy.
