......One of the choices is to decide whether to go with a 32-bit or 64-bit Windows 7.
What I've found is a 32-bit choice would limit memory to 4 GB.
But a 64-bit choice might limit what "old" programs could be run.
I wonder what other input some might provide who have already made this choice.

I'm in the same position as you, except my PC isn't dying. I am building a new one and I'll put my XP machine out to pasture or format the HD and give it to the Wife.
I wouldn't worry too much about older programs not running. I can't think of a single ham radio program I used going back to MSDOS that isn't done better with a modern version. And if you have a program that wont run it shouldn't be too hard to find a replacement program. The amount of software available today for ham radio is mind boggling and a lot of it is free!
I chose to go 64bit. The programs that most matter to me, EZNEC, PowerSDR/IF, JT65-HF, N1MM and DXLabs are all supposed to work on Win7_64. Win7pro and Ultimate have an "XP mode" that is supposed to allow you to run older programs.
