how do initialize the operation of a new ipod touch without itunes?

my computer, for some reason, does not want to finish installing quicktime programs or itunes. my computer tells me that it is unable to access network, therefore i am unable to completely install itunes 8.0. now, the ipod touch that i am trying to operate and access is brand new out of the box. is there any way to start using the device without having itunes to download applications into the ipod. what is my first,....last step to start using this wonderful gizmo? thx!!!
