Software installs for a fresh Mac

Here's a list of software I had to install to get closer to normal in the Mac:

• Firefox (with NoScript, AdBlockPlus, Greasemonkey, Ubiquity, Firebug, and Vacuum Places)
  
• Carbon Emacs
  
• Xcode with developer tools
• Quicksilver
  
• X-Edit 2.0 (for my guitar pedal)
  
• Nethack
  
• Crossover Games (running Steam and thus, Team Fortress 2)
  
• GarageBand extras
• GrandPerspective (hard drive dissector)

The terminal situation on the Mac seems pretty hopeless. I could use a good recommendation. I'm looking for Command-means-meta and high color, tabs would be nice. At this point I'm just running M-x shell in Emacs, but Emacs has problems in the remote shell (in particular, I can't get remote completions to work because Emacs consumes the Tab).
