With 2 GB of RAM as a maximum, there's no particular advantage for you to use 64-bit, even if your hardware would otherwise support it.
It's possible but highly unlikely that Ultimate would be worthwhile. Home Premium is all most people ever need.
Here is what Ultimate has that is not available in Professional:
BitLocker, BitLocker To Go, AppLocker, Direct Access, Branche Cache, MUI language packs, boot from VHD.
Here is what Professional has that is not available in Home Premium:
Domain join, Remote Desktop host, location aware printing, EFS, Mobility Center, Presentation Mode, Offline Folders, Group Policy (GP) controls, advanced backup, XP Mode, support for 192 GB of RAM, and support for 2 CPU sockets.
If none of those terms ring a bell, you aren't likely to need them.
