My Personal Finance Plan

[mikeyKay]

Alright, after reading this board for a bit, and reading some books and other sources of information I have formulated my personal finance plan. Before I pull the trigger and open the accounts mentioned below, I am looking for a little assurance that I'm on the right track.

Background:
23 years of age
Make 65k/year at a “stable” job
Made 157k in poker tourney
Anticipate making 30k this year from poker.
Presently maxing out contribution to 401k

I will put $60k into a tax-free vanguard money market account for taxes this year. I am in the middle of relocating and I will talk to a CPA, or gambling tax specialist once I am settled, and figure out if I can (and should) file as a professional gambler this year. I am unsure if I am allowed to file as a professional because I have a regular job, and I’m not sure about what kind of problems may come along with it (I know its not good to swap back and forth from pro to non-pro year to year). I have refrained from making quarterly payments because I think it may screw up my filing status for this year(???). I will make my quartley payments once I have that info. Anyone have any advice/info on this?

Investment plan
After paying off student loans, leaving enough money in my poker account and bank account, I can comfortably invest $60k. This money will primarily be used for a down payment on a house somewhere in the next 3-5 years. I want to invest this money in a vanguard mutual fund account with the following distribution:

25% VBIIX Vanguard Interm-Term Bond Index
25% VGTSX Vanguard Total Intl Stock Index
25% NAESX Vanguard Small Cap Index
25% VFINX Vanguard 500 Index

I am somewhat worried that this distribution is too risky and not diversified enough. Since I anticipate investing this money somewhat short term, I wonder if it should be distributed in a less volatile fashion.

Let me know what you think, and thanks for the help.
