It's not a good idea to post your email address on public forums, I've asked the hosts to remove them.
All content is tied to the account that downloaded them, and you can't currently transfer them to a different account. If you don't know the password to that account then you can try getting it reset via this page http://iforgot.apple.com . If you can't get it done that way then you can try getting access to the account by contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page. If you get access to it you can then change the primary email account on it to one that you have access to : http://appleid.apple.com
