In general we recommend not to reuse the old /home with the old configurations as they might conflict with what we ship in Maui.
What we recommend is, if you want to reuse the home partition to create a user with a different name (so it does not use the /home/oldusername folder directly but rather a new folder) and then copy/move the Images, Video and Music files over that you need. If it comes to applications (not the desktop) mostly you can also copy/move the firefox/thunderbird profile or other application configuration files and try them out if they work correctly.
