smokyjoe, you may want to look into the jailbreak app called pwnTunes. Its $6.99 from Cydia.
I'm not a user of it myself, but from what I understand it exposes the iPad as a USB drive allowing it to be connected to any PC without the need for installation of software. From there you can drag / drop files onto the drive and pwnTunes manages the process of putting the media into the correct place and exposing it through the Music, Photos, Video apps etc.
As I say, I don't use it, but it sounds like its the solution you are looking for, so worth investigating further.
