maybe you take a look at the cbt nuggets for video training and in addition you should get a simulation software. so you don't need to buy expensive hardware.
gns - router simulation
cisco offers also a ccna simulation pack
see at amazon
or maybe you get here
a freeware solution
for the ccna exam you need to know routing fundamentals (classfull, classless) and access list configuration. but the exam will change in the near future because of the new ccna courses (icnd1 + icnd2), which i don't know
cheers + good luck,
