Transfer of ownership/registration issues

Question

Can anyone advise on how to unravel the messy issue of transfer of ipod ownership, and problems with retaining music on the ipod while syncing with new itunes account.
My partner wants to give me her ipod, and we want to work out how to register her ipod to me, and be able to sych to my itunes. But can we do that AND;
1) retaining the music already on her ipod
2) situation rather confused by the fact that she has 2 itunes accounts set up (long story, but we had our pc's stolen and rather than reactivate her old itunes account she set up another one!). So the ipod is synched to both her accounts
3) she can't seem to have music from both accounts loaded onto the one ipod - is there anyway of doing that? She only gets the option of erasing what's already on the ipod and loading up the new account.
4) what we were hoping was to load all the music from both her accounts, and then register it to me
Any help, greatly appreciated!

Thanks for your response Chris, but things don't seem quite as simple as you suggest (or perhaps I have't explained the problem properly!).
Firstly, the ipod is already registered to her, but she no longer wishes to use it (therefore is prepared to hand over to me and 'close' her itunes).
Second, you seem to suggest that there is no such thing as an "itunes account" - I'm confused! What I mean is we both have music loaded under seperate Apple id's (both burnt and purchased, on seperate computers). Her music is already loaded on the ipod. What I'd hoped to be able to do is sync to my itunes library, without deleting what's already on the ipod (while I realise I can't transfer what's on the ipod into my itunes library, I was hoping to be able to at least keep what's there on the device).
It doesn't seem to be that simple. When I try to do this itunes warns me that to load my itunes it will delete everthing already existing on the ipod.
It seems an "either/or" situation - we either keep whats on there, or sync to my library.
