You could just buy the Cisco Press books and study it yourself. The two most popular authors are Wendell Odom or Todd Lammell, I gather Lammell tends to have a more conversational writing style, if that matters. The books come with PacketTracer on CD, along with practice tests and labs - essential stuff.
A CBTNuggets streaming subscription would be useful, very informative CCNA material enthusiastically presented by Jeremy Cioara.
You might want to aim for the CCENT first, it's about half the CCNA material and carries more weight than it used to after some recent changes to Cisco certifications, then carry on to get the CCNA with that under your belt instead of trying to do the whole lot in one go.
