I apologize if this question has been asked before.   I have a new
Thinkpad T61 in scheduled to arrive sometime next week.  I want to
install Fedora 9 on it.   Being as it has a Core 2 Duo processor, I
assume I can install the 64 bit version of Fedora 9.  My question is
what are the pros and cons that I need to consider when choosing 32 or
64 bit version of Fedora 9?

64-bit is faster (mainly because x86_64 has more registers to use) and it can run everything 32-bit can (almost all the packages in Fedora are available in 64-bit versions and there are multilibs to run 3rd-party 32-bit-only binary-only junk), so really there's no good reason to use the obsolete 32-bit version.

IMHO, it makes no sense to run a 32-bit OS on a 64-bit-capable CPU, especially for x86 (x86_64 is really a huge improvement).

Let me offer one, 32 bit applications are smaller and nicer to cache. Depending on the application that can make a difference. Also minute gains in load speed, memory using, probably too small to measure.
