As said before backtrack isn't meant to be your daily OS. There's a reason why there's no flash, networking interfaces not started, etc. As well as always running root. You need to take a more practical approach to Linux before you start skidding all over Backtrack randomly running tools that you don't even know the syntax, none the less understand how and why the program does what it does. I suggest getting familiar with Linux (since you want to use backtrack, go with Ubuntu or Debian as they are the base of Backtrack) and learn simple bash commands, as well as learn how to use google and the man pages available for commands and applications. Also its best to not install backtrack, unless you're installing it on a USB as persistent, otherwise keep it as a live disk/live USB.
