So after moving away from the cisco world for about 18 months or so im back

Various things came up which meant i was never able to complete studying for CCNA at the time, kind of feels like im starting from scratch but Ive watched a few of the ICND CBT videos and things are slowly falling back into place.
Has anyone else been in this situation where it feels you are re-learning things you did know but now are more than a little hazy??
Any tips for where to start again?
I still have some kit from 18months ago:
1 x 2950
4 x 2610
1 x 2611
1 x 2509
Of course the books I had are out of date

Looks like I need to buy the new ones which relate to CCENT / CCNA, the ones I have are the CCNA all in one and the INTRO / ICND ones...
So this weekend ill be dusting off the kit and watching some cisco videos - im sure the wife will be really please
