Hi freakygeek,
Given your timeframe, past GMAT scores, and score goal, you should certainly focus on building your Verbal skills. However, there is an opportunity to pick up some nice points in the Quant section too, so you should plan to spend some time building your tactical skills for that section of the Test.
With both of those goals in mind, I think that the EMPOWERgmat Total Score Booster would help you considerably. Most of our clients complete that Study Plan in well under 2 months, so the time commitment wouldn't be that bad. We have a variety of free resources on our site (
www.empowergmat.com), so you can 'test out' the Course before setting up an account.
If you have any additional questions, then you can feel free to contact me directly.
GMAT assassins aren't born, they're made,
