the app purchases are associated with the itunes account. transfering them to a different email address could be considered stealing the apps. you can get the music off with mediamonkey (hope this works for 2.2) and then just put it into itunes again and sync it up. but you already know how to do all of that. even if you backed up the apps somehow and put them back on there they would fail to work right unless they were modified and thats getting into illegal stuff. just redownload them. i know how to do what you want but feel like its too much on the edge of stealing that i personally dont want to provide more info. someone else may help you out though.
THis is the most i can give you
