I just started studying for the electrical/electronics and I think you should definitely get the practice problems from NCEES. I'm not taking the test until April 2010, because I feel I need the extra time to get up to speed again. I haven't hardly looked at a electronics problem since I graduated college in 1998. Anyway, I obtained several books off of eBay. Some that I have are the Schaum's books of Basic Electricity, Basic Electrical Engineering and another one I can't remember right now. I also have the Dr. Blanks DVD's which are helpful, but very dry(I just started them). They seem to be a good refresher so far, but I got the DVD's are before I knew they were going to change the format of the test. Anyway, they still have value, just not as much as before I think I echo the same as everyone here to work as many problems as you can. I did buy the new version of the EERM, edition 8 I think, but I haven't got far enough along working with my problems to know if its good or not. I think most people think they could have made it without the EERM. I have several others that I'll have to list when I get home.
What do you feel you skill level is? Maybe you just need to get the NCEES practice problems and see if you can work them. Then obtain your study materials from that point. I also ran across a couple of PE Refreshers offered by different colleges, on-campus and distance learning (DVD's), but they are very expensive. I can send you those links if you like.
