Sorry maxpowers I was busy preparing for tests until now.
Your V39 is in 700 range, you need to bring your Q score to at least 47. You can search for 700-ers here to study some V & Q combinations.
Since you have not touched the test for several years, I suggest to focus the improvement in Q side to the target score I mentioned above, and bring your previous V skills back.
In addition, since the Q side in GMAT is getting much more competitive these few years, because of more test takers from many countries with good Q fundamentals, a few wrong questions in Q section can cost you a lot. Hence the safer strategy is to bring Q to 47+, and at the same time try to improve V-side as-much-as-possible.
For more details, I suggest the followings: Get the latest OG guide (OG11) and focus on the Q questions (PS, DS). Monitor your hit rate of these questions - your hit rate need to be at least 85%. Analyze the wrong questions to identify particular weaknesses in a certain area, whether it is number properties, algebra, geometry, or something else, and work on those. DS is more important if you want to get over 45 - these questions are not difficult but are designed to trick people, so you must be extra careful and get good hit rate for this category.
For verbal, the goal is to bring your performance back to that of previous test. You can either do SC and CR questions in OG11 (the book has very good explanations), or get SC1000 and CR1000 from this site (for explanations for SC1000 and CR1000, you need to search in this site).
Good luck and hope this helps!!
