I wouldn't just dismiss the vocab words, especially if you're already feeling confident on the quantitative section. A vocab flashcard app on my phone was probably my single most fruitful way to spend an hour. I was really surprised at how many of the words showed up on the test, but maybe that's just me.
Overall I read a GRE prep book cover-to-cover about a month before the test, and I took 2 practice tests in the last week. Between that, the flashcards and refreshing some math concepts, that's all I did. I got 168/160/4.5 (V/Q/W).
If I had it to do over with limited time to study, I'd take more practice tests. Funny handle, by the way
