Congrats.
There are some free Hero type clocks you can get, which is nice.
Personally, I'd get these things
GDE (Application Dock is nice below a large hero clock)
Wallswitch
Google Goggles
Locale
Shazam
Beautiful Widgets (Its nice having weather, calendar and alarm clock in 1 bar)
Google Sky Map
Iheart Radio (if you care for this type of thing)
Nimbuzz (instant messenger)
SMS Popup and Handcent SMS
Spare Parts
Autolock
Battery Widget
Pandora
ScreenModeWidget
Ringer Toggle Widget
Pretty much, that list gives me all the functionality I need for the phone. Don't be daunted, its doesn't take long to download these apps. You can customize the phone to pretty much do what you want, stay on and turn on bluetooth when its plugged in, turn off the screen after 30 seconds when not plugged in, goto silent when at work, use the volume rocker/camera button to turn on the screen, etc etc. There are a ton of options, play with it.
Good luck.
