Oh, good, you do know a lot about your strengths and weaknesses!
Just FYI - you start with a list of percentage correct. That's really not how the test is scored, so that's not necessarily a great indication of strengths and weaknesses. (It's directionally accurate, obviously, but it's not the primary factor you should be considering.)
Are you using our 2007 edition of the RC and CR guides or the older one (one book that contained both)? If you're using the older ones, I really hate to suggest that anyone spend more money, but the newer guides we just published a couple of months ago are substantially better.
I don't know where you're located but if you can get to a Barnes & Noble or other big bookstore, you might want to drop by and browse through the new ones to see if they would be of more help to you. (The two topics have been split into two separate books now.)
Another thing you don't mention but that is crucial to doing well on CR and RC is a thorough understanding of the wrong answers. Are you spending as much time understanding why the wrong answers are wrong as you spend understanding why the right answer is right? A large part of CR and RC is simply process of elimination - you find the four wrong answers and cross them off and whatever you're left with is the right answer.
If you are struggling with identifying assumptions and getting the structure or pattern of the argument, then trying to spot the wrong answers, rather than the right answer, may really help you.
It looks like you're also, in general, spending a lot of time reading on both CR and RC. Here, you really need to make sure you're only getting the basics, especially for RC. DON'T get into the detail, DON'T try to understand every last thing in the passage. Just understand the high level stuff - what's the one sentence you could use to summarize each paragraph? If you can answer, or even begin to answer, any detailed questions without first having to go back to the passage and figure things out, then you're reading too much on your first read-through. You just want to know where the detail is located on your first read-through, so you can find it easily if you get a question on it - but you don't actually want to understand it at that point. You'll try to understand if (and only if) you get a question on it.
Remember for RC that you will only get 3-4 questions for a passage, though they will have written 6-8 questions overall. So you won't get questions about everything that's in the passage. (You will see all of the questions in the OG - but not on the official test.)
Also, as much as possible, work from OG. This is true for the whole test, but particularly for RC and CR because there are no facts to work from here. It all hinges on the language of the question-writer and how s/he structures the passage / argument and question(s), so you need to make sure that you are working from the actual source. Don't use 1000 CR. And I wouldn't spend too much time reading articles / editorials, either. Go to the source - OG. Pick those apart until you start to get a feel for how they write the passages / arguments, how they write wrong answer choices, what things are intended to be traps to get you to pick the wrong answer, etc.
