Well, here I am! I'm all set up on my brand new iMac!

This keyboard's gonna take some getting used to, I'm making a lot of typos...
Aside from my dad being a nervous pain in the ass through the startup, everything went great! When I bought it it had Tiger on it, but there was a Leopard DVD included. The leopard installation took a while but near the 11 minute mark its timing was actually pretty accurate.
My apprehension on the screen resolution was totally unfounded, my sprite comics and everything looks just as it did on my old screen in 1024x786(or whatever the resolution was. I'm too lazy to check)
Everything's great so far. I've had absolutely no problems. The only thing that bothers me is the brightness of the screen, which I'm not used to at all.
Aside from that, I'm completely enjoying this iMac. Every worry I've had has so far melted away, all I need to do is unpack everything from my external HD and adjust to the OS and I'll be completely set.
Thank you all again for the help.
