I'd put "from twisted.internet import reactor" outside of the loop.

Yes, you can, you should be able to call connectTCP any time before
the reactor is shut down with reactor.stop().

The first thing I saw is that you'll want "reactor.run()" after the
loop, otherwise that code won't get run until the system is ready to
shut down.
