Advice needed!

I will start preparing Verbal section in a few days, so I need advice from you guys.
Books that I will use are:
-MGMAT SC
-PowerScore CR
-For RC I will basically continue what I was doing during my math preparation, just read a lot of books and magazines. I really don't have a clear strategy for RC...
Also, I bought e-GMAT Verbal Live Prep course...

I want to ask for advice...
Should I first go through all the books and then start using the course, or learn simultaneously, or... any suggestions would be invaluable...

Thank you!
