GottaBeKiN,
Maczen makes a good point - learn from it but do not spin your wheels - the trouble with Cisco is that you have so much to know - sometimes you need to wrap your head with duct tape so it does not explode!!!
Take the cards - put them in a static bag, print the docs that you found on them and then put it all in a box and mark it for later use
Trust me as you read your CCNA stuff you are going to want to keep investigating more and more - if you are NOT interested - you might be in the wrong area :-(
As I always told my students - the routers, switches, IOS etc that they are using ---- is ALL THE SAME as what the CCIEs play with - they just KNOW IT ALL

Cisco does not make seperate routers and IOS for CCNAs
You can not learn it ALL (right away) if you could and did - you should be testing for CCIE!
Get your CCNA rack together and get back on the Sybex book, if you have not already done so download the FREE PDF lab book that I posted about and start working through those CCNA labs - get your fundamentals down and get the CCNA behind you!
Try not to drift too much - CCNA is more then enough to know as it is - I have seen some very bright students fail the CCNA several times because they were distracted by EVERYTHING else!
Good luck!
