wicd has a curses interface that you may find helpful. On the other
hand, I connect via shell with ifconfig, iwconfig (to set the interface)
and dhcpcd. Briefly...

ifconfig (interface) down
iwconfig (interface) essid (X) key (key)
ifconfig (interface) up
dhcpcd (interface).

with differences regarding the type of connection.

You can create a root script, one per profile/connection, running this commands.
Read the man pages, it's easy. It's a pity Archlinux's wireless tools are not
available in Debian, as they are great cli-tools.

Never touched it (only on buggy hardy heron). I think wpasupplicant is
activated through dhcpcd (not sure). And I never really liked the
interfaces file. My problem.
