All T61 machines are 64 bit and can run a 64-bit OS. There is no such thing as 32 bit -> 64-bit upgrade. It needs a fresh install. The same license is good for both, but you would need recovery disks. T61 machines are not all the same: 14.1: tall-screen (4:3), 14.1" wide-screen and 15.4" wide screen. There are difficulties in getting a fresh win 7 install working, related to system update. Microsoft has not paid much attention to windows 7.

What richk said plus...
1. AFAIK all T61 models came with WiFi, some 801.11a/b/g and some 801.11a/b/g/n. However, since these systems are several years old it's possible that the WiFi card may now be missing or defective.
2. If you're considering buying a T61 beware that some models came with integrated Intell graphics and some with a discrete NVIDIA GPU chip. The latter chips are notorious for failing, thus rendering the motherboard useless. I would avoid those models.
