Here you go:
1. Intel Core Solo - single-core CPU, becoming obsolete.
2. Intel Core Duo - Intel's first try on double-core CPUs, generally enough to work and play.
3. Intel Core 2 Duo - overhauled Core Duo. Lower-power/heat version (laptops, etc). Still DOUBLE-CORE. Different sources report performance boosts from 10% to several times (depends on tasks you do I guess).
4. Intel Core 2 Duo Extreme - high-power/heat version of Core 2 Duo (desktops, etc.). Not really much faster than plain Core 2 Duo.
My advice would be - if you can afford Core 2 Duo, get it, as it is better than Core Duo. On the other hand, if you get Core Duo, you're not going to suffer...
Check this:

As for Vista - well, I'm using Vista since RTM release, about a month or so... Generally, usability is better but it needs lots of tweaks and patches yet. And it doesn't really designed for games, too much bloat...
I've seen good advice on Vista - DO NOT BUY VISTA ALONE! Wait and buy it as OEM version with new computer, when it becomes available. This way you will be sure that computer will run it OK and get it much cheaper.
XP will do just fine for next 1-2 years. If you still decide to go Vista way - you can download RTM version and run it legally for 30 days (or longer, but it's not legal
). You will need at least 1 GB of RAM (2 GB better) to run it.
P.S. I run Vista on my home laptop: Core Duo 2 GHZ, 2 GB RAM, SATA HDD, ATI X1400. Works fine, I even play BF on it.
