Well, SplashData is making their applications for the Pocket PC now:

...so have you contacted them to ask if they're porting SplashMoney over to the Pocket PC?
I'm not sure about your first request - there are dozens of list-making programs out there (try searching Handango), but I don't know which one matches up with the app that you're used to using. Odds are, none of them will be exactly what you're looking for and you'll need to adapt to using a new one. ;-)
