Boot Camp

First of all I'd just like to say sorry If I posted this in the wrong section... Feel free to move it mods...
Anyway.
I will be buying a new 24 inch iMac and I have serveal questions about bootcamp.
Am I right in saying I will need to buy windows xp SP2 for it?
If so is this suffcient?

If not please can you tell me what is?

Also, In bootcamp or VMfusion, when I run a program would it run faster than my old PC? My old PC is a single core and 1 GB RAM...
The iMac im getting will be dual core, and have 2GB RAM.
Will this speed up programs even on bootcamp and VMfusion?

Thanks so much for any help in advance.
