If I buy a duo core / 64 bit processor and install Windows XP Pro on it, does it do any good? Does regular XP use the second processor or do I need a 64bit OS?

Dual Core and 64 Bit are two different things, though they are combined into one processor.
XP will use both cores automatically, but you will need a 64 bit O/S to use the full capabilities of the processor, which will revert automatically to 32 bit (still using both cores). I have heard some people claim that this can cause performance issues, but I haven't had any problems myself.
Even if you get a 64 bit O/S, you won't notice any real gain, since there aren't really any 64 bit applications out there yet (well, at least not any that you are likely to use).

Yes it does. Here is what Microsoft says:
Both Windows XP Pro and Home will support both dual core and quad cores processors as long as they are on the same processors. There are no additional licensing fees per core. But when you have a system using two processors, only Windows XP Pro supports this function.
Microsoft states officially:
“Microsoft Windows XP Professional and Microsoft Windows XP Home are not affected by this policy as they are licensed per installation and not per processor. Windows XP Professional can support up to two processors regardless of the number of cores on the processor. Microsoft Windows XP Home supports one processor. ”

They do make a 64 bit version for XP SP2. You would probably get more funtionality benefits and the processor will be quicker and overall performance may be high to moderately noticeable in difference compared to just using XP SP2 pro or home.
If you decide on XP, use XP pro not Home. It provides the best range of being able to "tweak" your system the way you want it. XP 64bit would be the best for your system though

I've heard that it allows you to perform resource-intensive operations, like recording to a CD or DVD, while still doing other things such as surfing the web or using other software. I'm sure you still need a good amount of RAM (at least 1 GB these days) to see a real difference.
I'm looking into dual-core processors for a person who is paralyzed from the neck down. I've heard reports that his voice-recognition software (that runs all the time in the background and devours resources) would work better alongside his other work. Not sure about this, but I think it's worth a try.

It's a major factor in Windows XP. Reliability and stability is what you get from the dual processors. Fast render on applications and programs.

It's a considerable difference on XP. You don't need a 64bit OS, 32bit is fine.
