Investing and planning

I received my tax refund on Friday. Together with my paycheck, I used that to start my account at Vanguard (VFINX). My initial plan had been to invest my first $3,000 into an "income" class fund. This is classified as a large blend fund, however, and I think I'm comfortable with that.

Once I have $6,000 in that fund, I will split it into a growth fund (VIGRX?) and an income fund (VIVAX). This will allow me to keep $3,000 in a relatively low-risk account for a financial catastrophe while using the bulk of my money to try to obtain a better rate of return. Eventually, I would also like to add in a small/midcap blend fund (VEXMX?) and an international fund (VGTSX?). Thus, I need $9,000 more to set up my portfolio the way I would like it. If I really stretched, I might be able to manage that by the end of the year. More likely, I'd like to have all 4 funds purchased by May 1, 2009.

Meanwhile, I am adding $50/paycheck to this fund. Additionally, at the end of every month, I plan to transfer additional "leftover" money (hopefully at least $400) to the fund. I'm expecting this to become the primary location for my mid- and long-term savings. If I can average $500/month, I'll be on track to seriously consider purchasing property of my own by the time I'm 30. Being debt free and a homeowner at 30 is a nice dream!
