Thanks for all of the advice, everyone.
Basically I'm just looking to further my own understanding of Orthodox theology and history. I was a philosophy major in college, and I guess I'd like to move my understanding of philosophical issues into a more Orthodox framework. If I ended up doing anything with the degree, I might be interested in teaching or academic work of some sort.
So, given that, are the smaller seminaries ruled out? I have read that Christ the Savior (ACROD) in Johnstown PA has a program for laymen, but I don't have a good sense of how advanced it is compared to Holy Cross or St. Vlad's.
