Thanks @jbarwick, for the TSP break down. It looks like a decent start, though I wonder if it's too much stock.
What about the Roth TSP? I can contribute to both, and don't know whether I should. Also, any opinions as to whether I should readjust this "one-third of my income" idea and consider outside savings options?
Also, I'm not familiar with the tradition of this thread, but should I keep posting here, or send you PMs in the future?
