I am not sure about the CR but regarding RC, I feel, if you have time then you should go for LSAT RCs. In fact, I found the following on your thread, "tip of the day":
When you're doing RC and CR when you're practicing, go through and eliminate every wrong answer. Give a convincing story for why each is wrong. Do this instead of simply finding a good fit and moving on. On test day it will make things a lot easier.
For CR and RC I found that doing LSAT material really helps. RC on the LSAT are very, VERY long and full of info so you'll be relieved when you get back on the GMAT train.
OH BTW! when I did my verbal I had enough time to read every passage twice, why? because I had gotten used to insanely long LSAT passages.
Personally, I am weak in RC. I am doing as many RCs as possible from 1000 RC series, which has RCs from GMAT, GRE and LSAT - exhaustive set. Actually, I wanted to recommend everyone, especially who is weak in RC, to do RCs from this series rigorously. That builds your stamina and makes you familiar with divers topics.
