Tips
Mail is a great program, especially if you go through the rules under Preferences, and set them up. The Junk filter should be set on training mode first, to make sure its not junking things you would like to see.
Safari is a very good program, the tabs are very useful but they must be engaged using Preferences and you can set up pop-up blocker using Cntrl-K.
The dock is very useful, you can use it to hold all the Applications you consistantly use, but you can store the Applications folder and your Home folder next to the trash when they can easily be accessed.
System preferences is a single Application that runs all the Control Panels and allows you to control things like Network connections, Desktops pictures, etc.
When you get to print, the Print Center Application will appear and will handle all your printing needs.
Appleworks is good, but could be better, if you need Office, get it using the Educational discount, but for many other things there are great freeware/shareware apps out there. I would suggest MacJournal.
iTunes is one of the best programs ever, play with it a lot, and make sure to rate songs and use the Smart Playlists. Also, go and get Windows Media Player, and Real, you will need both eventually, but otherwise Quicktime rocks.
Make sure to set up one account as an administrator, but all the others should be users, and don't lose that Admin password, you need it to install software and to access your volumes from a different machine. But, truly OSX is the best OS out there, you should have a blast. Let me know if you've got any specific questions.
