Hi Morgan-

Maybe a little late, but here's a little tutorial I've been working on that might help:

The rest of this chapter gets heavy into what David is talking about (and using objects!), but it sounds to me your problem is little simpler than that. But, you should definitely try to wrap your head around the difference between plotting in lat/lon and "plane" space. In short, the projection and ellipsoid you choose helps define that coordinate transformation. Basically, if your data is in lat/lon space, you can choose whatever projection/ellipsoid you see fit.
