I want the user to be able to press Tab at certain points and offer completion of values.

Well, I suggest that you use Emacs to run your command line Ruby app. In Emacs, my SO friends just recently helped me to solve the Autocomplete tab completion (here and here). Autocomplete seems to be the most intelligent word completion tool to date.
