You could try the Files and Settings transfer wizard (In Start, Accessories, System...) and see if that works for you. I'm not aware of any tools off the top of my head, but (on principle) I would not rely on any auto-complete/password storage to ensure I could do my day-to-day computing.
There are plenty of tools which help in this area which are guaranteed to provide better support than Microsoft will. Things like KeePassX (for password management) and (while I don't use it, I've hear good things about) Roboform are supported by communities who are invested in a long-term solution. I would really try to migrate to a new solution. Anything else would be putting a band-aid over a festering wound.

Good luck! :)
