wow...seriously overkill, and a lot of money. you'd be better of saving the money for the exams, retakes if you're not too confident, or a class, which would have a lot of the equipment you'd need lying around, just check for cisco netacademy's hell, i did all fou semesters of the CCNA in high school for free, and at least in Texas its' offer at some community colleges for reasonable prices.

but a decent CCNA lab would be a 2600 two 2500 (for real cheap ) and a decent switch with a couple of wic2t's. The most expensive thing you should purchase is the switch so you can play with the vlans and trunking protocols. But one thing at a time, get the CCNA before you fiddle with the CCNP so you don't waste money on something that'll be outdated by the time you go for the CCNP.
