Welcome kurtzoe (or do you prefer Fuzzy?). If you haven't found them already, we have a helpful list of things to think about before you make the leap:

There are other folks here who are more equipped to answer your Firecalc questions than I am.
Out of curiosity, how did you pick $500k as the amount to put into DW's pension account?
If ASAP means at the end of the school year, you don't have much of an opportunity to get a better handle on your expenses, so it will be important for you to track things very closely the first couple of years to validate your assumptions or adjust accordingly.
Also, you don't mention your asset allocation on the portfolio, which will be an important factor in your success. Many of us would also use low-expense funds to keep the investment fees below 1%.
Hope this is somewhat helpful.
Oh, and feel free to join the
Class of 2017!
