Short quick summary: There is no benefit you'll see to using the 64-bit 
Ubuntu.  You'll prefer 32-bit because of better support for proprietary 
software and no detectable speed difference.  (That's true unless you have
>4GB of RAM, etc.)

Also, no, you can't straightforwardly "upgrade" a running system from 
32-bit to 64-bit.
