<human>: Can you succinctly summarize the text in 1-3 sentences?

As a public school teacher I am apart of the California State Teacher's Retirement System (Calstrs). I put 8% of my salary into the pension, and my employer matches that 8%. That's how it works for all teachers. The average rate of return for the past many years on that money has been 7% per year. As of now, I have a smidge over 11K in there. 

On to the meat of my question - I DO NOT want to rely on Calstrs alone when I retire. I don't pay into social security, so I won't get that when I retire (not that I would rely on that anyway). My wife has a shot at getting employed this fall, and if she does, out budget will allow us to each contribute 425 per month to some additional retirement account. What that should be, I do not know. I have looked at and thought about a Vanguard IRA, but I feel like I'm just taking a stab in the dark with this.

For what it's worth, here's our current financial breakdown:

Take home pay: $2,100 per month
Expenses: $2,050 per month.

We have a healthy emergency fund that could sustain us for 4-6 months, depending on how frugal we wanted to be. 

If she does become employed, our take home pay would increase to $4,800 per month and our expenses would increase to $3,200 per month (the added cost comes from child care and the increased gasoline usage). We want to use the additional $1,600 per month to start saving for a house, and we want to start contributing to our retirement fund. 

We do live in the San Francisco Bay Area, so a mediocre house in a mediocre neighborhood is going to run us a minimum of $300,000. Our plan for a house is to save 80K for a down payment, and for us to take out a 20 year loan (possibly 30 year loan). We know we won't have enough for a house for quite awhile, but we're okay with that.
<bot>: I really need advice on what type of retirement account to start putting money into ($425 from me, and $425 from my wife).
