Lobo66,
As for "good practice package" - I assume you are looking to take the CCNA, get 2 good books, one from Cisco Press and the other the Sybex CCNA Study Guide by Todd Lammel, latest copy just came out in the end of April, $30 at Amazon.
You also need tons of hands on practice, best is a lab with 3 Cisco routers and 2 switches, but you can also look into a good sim or some of the free emulators; you can "Google" and learn about!
Good luck and stay away from TestKings !!
