I passed Network+ today, 725. Not as good as I'd hoped, but only 1 1/2 weeks of study. I used mostly Sybex Network+ ISBN: 0-7821-4406-3, and read a little bit of Exam Cram2 ISBN: 0-7897-3254-8. I'd say the Sybex is way better of a book though.
I had a few questions on ports, so know the ones on this site. Also, you should know troubleshooting, i.e., slow networks, no link light, disconnecting a client from a physical bus.
Good luck, study up.
