It's an Athlon64, so its 64 bits. Vista 64 will install. 2.0 Ghz may not be the fastest Athlon on the block, and those 2 GB are meager for running Vista.

Installing a 64 bit OS would be worth it, especially if you upgrade your RAM to at least 4 GB. Depends on the mainboard whether that can be done. With a bit of luck, you have an AM2 version of the Athlon64, which means you can use DDR2, that's dirt cheap at the moment.

XP 64 bits might be a better idea. Less resource hungry than Vista 64 bits, but you may run into driver problems. If your graphics card is an ATI, you can forget about  XP 64 bits.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
