As for verbal, I'd say look into GMAT Fiction and buying materials to supplement your weaknesses:

Two weeks isn't much time, but your math score is pretty close to the 80 percentile. Verbal is where you'll need a little more of a boost.

This paragraph troubles me. A stated goal of 779 suggests a fundamental misunderstanding of the scoring system. And with such a high target score, this puts unnecessary pressure on you during the final two weeks and may cause you to try too much and burn out right before the exam. While it's certainly possible to see a good bit of improvement toward the end of one's studies, a "drastic" 100-plus point increase in two weeks is extraordinarily rare.

So my advice is to not go down that road. Instead, consider mohater's input and put more focus on verbal (without forgetting about math, of course). Go over the OG and reread as many explanations as possible, be active on the verbal forums (answer questions and defend your choices), and reread guidebooks. Also heed udvranto's warning and reserve the last two days of your prep for relaxation and rest.
