The biggest change I might make to your plan is to consider taking a CAT before you start your review, if you haven't already. Without knowing where you're starting, it's hard to say if you're going to see the improvement you're looking for. Even if you're weak on quant, chances are that you aren't necessarily weak at all quant, so it's important to know where you should be concentrating your study time so you can make sure that all the effort you're putting in isn't going to waste on topics you know well - or that you aren't assuming that you know information well that you really don't.
The answer to your direct question - whether you have enough material - really depends on a couple things. If you are keeping a detailed
error log where you really take the time to analyze (and learn from) your mistakes and are treating the practice sets as meaningful practice rather than rote practice, then it might be enough. If you aren't, then it might not be. My advice would be to use what you have and then re-evaluate. At
ORION, we really suggest trying to re-evaluate every few weeks since sometimes improving in one area (like ratios) is going to mean that you're going to improve in related areas (in the case of ratios, that might be percents, probability, etc.).
