Do I need to have both components to support 64-bit, motherboard and CPU. Or is it just the CPU that matters?

To quote Microsoft (eh),

Windows XP 64-bit Edition requires a 64-bit motherboard and chip set,
available through Intel and several OEMs.

In general, it helps to understand how a 64-bit system differs from the 32-bit one.

The first couple of pages from this old article are also a good read,
64-bit computing in theory and practice AMD and Intel make the leap to 64 bits

A motherboard usually supports some kind of CPUs and may not support some other kind. So, if a motherboard supports X CPU which happens to be 64-bit then it is supported, but that doesn't mean that it will support Y CPU which is 32-bit.

It really drills down to what models of cpus a motherboard supports regardless of 32-bit or 64-bit. Check the motherboard's manual to know which CPUs are fully supported.
