Q. Is it true that VMware Workstation 7 can run 64-bit guest OSs on 32-bit host OSs?

A. If you're running a 32-bit OS on a 64-bit platform that has virtualization (Intel VT or AMD-V) enabled in the BIOS, then it's possible to run a 64-bit guest OS with Workstation 7, even if the host OS (the OS installed on the actual hardware) is a 32-bit version. Ideally, however, you'd want to run on a 64-bit host to maximize the performance of the physical and virtual environments.
