Well it sounds to me like you know that timing is the issue for you, so I would go back through all the questions that you had timing issues on, and make sure you can solve those in less than 3 minutes. NEVER SPEND MORE THAN 3 MINUTES ON ANY QUESTION. If you do, you may miss out on questions you would have gotten right otherwise.
So work on getting the 2 minute feeling on all quant questions, and guess at 3 if you aren't RIGHT at the answer.
Other than that, it looks like you've been doing really well on your practice tests. So it would probably help to stay warm, go through some practice questions, reinforce the concepts you know, and get down the concepts you aren't 100% sure about yet. I would probably not study too hard, b/c you don't want to burn out right before the test.
I would also find a subset of about 10 easier questions (from both quant and verbal.. maybe one or 2 of each type minus RC), and take those the morning before you leave for your test. This will help with getting your brain warm, and boost your confidence as you get them right.
Good luck! and let us know how it goes
