Ask away... you're not the first, and I doubt you'll be the last to ask me Mac questions.

Here are some great free apps I recommend that all Mac users get:

VLC Player - Plays just about every video format
Handbrake - use to rip DVDs to your computer for simple viewing in VLC
Cyberduck FTP - great, full function FTP client
Text Wrangler - killer text editor
Mac The Ripper - use to copy DVDs; it rips the DVD to your hard drive in a format ready to be burned back... and removes copy protection.
xACT - used to convert .shn and .flac audio files to .wav or .aif, or vice versa
Flip4Mac - allows you to play Windows Media .wmv files in Quicktime
Audacity - basic audio editor
OnyX - allows you to run a variety of system maintenance scipts.

Firefox or Camino or Opera web browser, as well as Safari which is built in.
