Clayton, welcome to the board. You have a few months to get your head wrapped around the unplanned change. Definately read the FAQ and best of boards.
There is much discussion on SWR (safe withdrawal rates) and 72T rules. Be sure to run your plans through FIRECalc as well.
Hope to hear more about your transition.
