This thread is a bit old for this kind of question (assume OP already has it sorted out), but in general, I don't recommend sync with iTunes. Manage that stuff manually as much as you can. I love my iPhone / iPad, but iTunes is a horrible application, and it seems like every update makes it worse. Last time I used a current version (the one on my computer is several revisions old now) I couldn't find any
thing. I consider myself rather adept, but I have no freaking clue how they expect Grandma to find some of the options I was looking for. Egad!
I use the native OS photo import to bring pictures from the iPad to a computer. I rarely download photos TO the iPad, and sometimes letting it sync just one folder
is OK for this kind of thing, but boy will you feel the pain if you let iTunes sync your media willy-nilly.
If I see that **** pop-up one more time..... "This device is currently synced to another iTunes library. Would you like to nuke all of your precious data and sync it to this computer? You can say no, but if you do, I won't let you do anything with it at all. So basically, delay the inevitable if you'd like, but you'll have to say yes eventually. C'mon. Do it. DO IT. Let me watch you weep."
