dude, megacharger, you're just like me.  I just finished building my first pc today.  I went the AMD route however.  I researched for a while, talked to people who knew what they were talking about, got a good general guide from motherboards.org, gave myself a full day and did it.  I had very few problems.  The heatsink was tough to get on (I was wafraid I'd break the CPU) and the first time, my HD wasn't recognized.  Other then that it went smoothly and was a lot of fun.  Oh and newegg is great.
My specs are:
AMD Athlon XP 2800+ Barton
Asus A7N8X Deluxe
Radeon 9700 Pro
Lite on CD-RW and DVD-ROM
some other stuff I just dont feel liek typing anymore.
good luck, and if you have any questions just ask
