What is the best learning material(s) for $500?

I'm assuming this would be a hard sell with your bosses, but given a time machine and 500$ to give myself back when I started studying, I would advise me to buy the following:

An Ipod Touch
Anki for the Ipod Touch
Daijirin for the Ipod Touch
A copy of RTK
A copy of "Common Japanese Collocations"
Whatever books on grammar I thought were necessary/appropriate
