Welcome, Casey. I am a graduate student in religion, too. Graduated with my M.T.S. in May and am working at a Th.M. that I have no intention of finishing!

I have found GTD to be highly adaptable to my messy academic life. For me, getting the rest of my life organized to the point that I don't worry about it is the biggest benefit. But, I keep a Next Action list of assignments that I have to do (reading, translating, preparing presentation, research) and I have an "Academic" group in my iCal that gets synced with KinklessGTD's action list. Nik (sorry I don't have the rest of his info right now) has a KGTD2Go Applescript to export each context to its own directory of notes on an iPod, which is quite handy for me as well although I think Ethan may have wrapped that functionality into 0.8; we'll wait and see.

Another thing that has helped me is to only carry one book to work from at a time. Right now, I am in an exegesis of Romans where we are reading Philip Esler's Conflict and Identity in Romans and James Dunn's Word commentary. I am also doing a class on Baptism & Eucharist in Early Christianity and some uhm.... refresher work in Hebrew. I decide when I am heading out the door which text gets my attention for the day. If the reading assignments are short, then I start on the next one. I never carry more than one with me; otherwise, I get sort of discouraged by all I have to do.

Anyway, that's a really really long way to say, "Yes, get the book and read it." Buy it if you can; I got hold of it through interlibrary loan and read through it rather quickly. If you aren't going to buy it, take extensive notes. Get the audio version if you can and rip it to iTunes. It's worth the read even if you don't implement it fully. Once you read it, take your notes and sit down and think about the way it needs to adapt to your situation. If you are at your computer pretty much all the time, an @Computer context won't really help all that much. But @Reading, @Research, @Library, @Writing, etc. will help immensely. There is a thread about this sort of thing already on the board, but if you want to talk about it specifically in relation to religious studies, then shoot me a PM or email or some such.
