For the Cisco stuff you start with the CCNA. The easiest path is to take the INTRO exam then the ICND exam. This is also the most expensive. $125 / each. The quickest way is to just take the CCNA exam. Still $125 but only one test. The CCNA is more difficult though. I would recommend using Cisco Press or Sybex books that were authored by Todd Lammle. That guy is THE MAN when it comes to Cisco and preparing you for the tests. When I recertify I always use his material because he makes it so easy to read, not dry and boring (or no AS dry and boring). Either way you go, the books I recommend are the INTRO and ICND books for whichever test path you choose. They work individually for the seperate tests or together for the CCNA exam.
Keep in mind that the CCNA exam changed in October so make sure the books you get are current. Nothing like studying for an exam only to sit down and find out some things have changed from the books you studied.
Also, some hardware time won't hurt either. If you know onyone who can help you out with that, then definitely take advantage of it.
For an easier route (since you're looking to do it through college), maybe study and pass the A+ exam and get a job in harware service / repair. It's not really "easy" per se, but it isn't anywhere near as tough as the Cisco certification.
As for books, your library will rarely have the latest versions of them available. Talk to people you know or use Amazon or ebay and buy used. Borrowing is much better (read: cheaper). Good luck!
