Windows 7 32 bit can run on both 32 bit and 64 bit processors whereas 64 bit Windows 7 requires a 64 bit processor. Most of the modern processors are 64 bit (right from Intel Pentium D). A 64 bit Windows 7 will be able to use more RAM then 32 bit Windows which has a limit of about 3.5 GB of RAM.
You cannot run 64 bit applications on 32 bit OS but a 64 bit Windows can run 32 bit applications. But before installing a 64 bit OS , you must make sure that you have 64 bit drivers for your system.
As of now, you should consider switching to 64 bit only if the software you want to use has a native 64 bit build and you are sure that it will provide large performance advantage.
You cannot upgrade from 32bit Vista to 64bit Windows 7, you will have to buy a new copy.
