+1 on brew and cask. Also, xcode, Tunnelblick, git, etc. Be sure to change your default path to put /usr/local/bin first, so that all of the brewy and other goodness you install is actually picked up - and, if you install a more up to date bash, be sure to change your shell: System Preferences, Users and Groups, "two-finger" or "right click" on your name in the list on the left, advanced options.... I'm happy with the default terminal, works well enough. EDIT: Not sure whether you will also need to change the default shell used by Terminal: start Terminal, Terminal, Preferences....
