from the quantity of material you've mentioned, i suspect that one of your principal issues may be that you're simply studying way too much, while not making more of an effort to
understand the core nature of the problems. especially in critical reasoning and reading comprehension, remember that extensive studying isn't really worth much; success on those problem types is mostly a function of three things:
1, the intuition and common sense that you already have from dealing with real-world situations (especially on cr)
2, the ability to understand the organization and relationships in a reading passage
3, the ability to distinguish relevant information from irrelevant information
the items in this list are not things that can be improved by raw practice or rote memorization/repetition, regardless of how strong your work ethic may be.
a couple of questions:
* when you say that you have "gone through" these materials -- especially in regard to your having gone through the og twice -- what exactly does that mean? have you just been solving tons and tons of problems and checking the answers, or have you spend effort trying to understand the general nature and purpose of the problems?
* how many days per week have you been taking OFF from studying? this is really important -- if the answer to this question is 0 or 1 (especially if the answer is 0), then your study habits are actually inhibiting your brain's ability to develop the kind of lateral reasoning required for these thought processes.

also, don't use rc99 -- the passages in that source have been taken from sources designed for the mcat, which is a completely different test, and so will actually work
against your gmat rc efforts in general. (mcat passages generally consist of clusters of random facts and very rarely have true main points, so they are not useful for the kinds of questions posed on the gmat.)
there's also the issue that the passages in rc99 have been stolen from other sources, mostly kaplan mcat books, although that issue is largely irrelevant to students.
