I agree wholeheartedly with nktdotgupta and Defiant1: since you're not applying this season, you might as well wait until you're completely ready.
The CFA is pretty nasty and I know that it's going to be tough to keep your GMAT studies going, but there's no point in rushing your test date. Be systematic in your GMAT preparations, get TONS of verbal practice (retired LSAT tests might be a good supplement to the materials that nktdotgupta mentioned if you need extra RC and CR questions), and take the test once you're consistently scoring in your desired range on the practice tests. If you choose an arbitrary, early date, you're likely to end up with a $250 practice test experience.
You're obviously making progress really quickly, but keep working at it, and be patient with the GMAT. Some people need several months of study to get into the 700s... and there's no shame in that at all.
Good luck with your studies!
