Well hello there!
Where are you applying to?
I'm applying to both PhD in Lit AND PhD CW/Lit (I call this hedging my bets. Others call it crazy)! So nice to meet you! I'm technically a creative non-fiction writer, but there are very few programs that offer non-fiction as an option so I'm also submitting as a fiction student (I write both). I've taught, published (only a TINY bit), and am interested in teaching non-comp classes... hence the PhD.
The GREs really chap my a$$. I'm taking the regular one this Thursday, and the Lit. November 13th. Aside from the stuff they sent me (for the Lit. test), I've checked out a few websites. This one, http://www.duke.edu/~tmw15/index.html, has by far been the most helpful. Starting Saturday it's all read, read, read, to try to re-familiarize myself with literature from my undergrad (which seems eons ago now...).
While I'm hoping to do well, I'm kinda of the opinion (at this point) that they're a touch superfluous. That being said, I don't want to give adcoms a reason to reject me so... study, study, study!
As for SOPs (I'd be interested to know how you plan to attack your SOP for the creative writing programs), personal statements, and analytical essays---working on it. Most are in some state of revising right now so we'll see how it works out I suppose!
