<human>: Hey all, I am very new to investing so have patience. 

I am a single 23 year old just out of college with first real time job. I am interested in managing my finances a little better and I have come here for some assistance.

I recently received a gift trust of $17,000 that matured and rolled into an American Century All Cap Growth Fund (TWGTX).  After looking around here I came to the decision I would move those funds over to Vanguard so I could take advantage of their low fee mutual funds. I moved everything over using an in-kind transfer(now at $19,000.  I would like to continue to invest about 75% of that previous fund in something similar that Vanguard offers. The other 25% portion would be allocated to an IRA. Not sure what type to use, Roth vs traditional. With my current job I have a Vanguard Target Retirement 2055 Ret Opt fund of which a contribution of $5000 was already made through my new job, this fund is by Trans America, I plan on contributing $150 monthly to this account. A past job created a 457 OBRA-PST, however I am no longer contributing to that fund because of the new job and it ended with a balance of $1,000.  

What are the next steps I could take to stabilize and organize my finances? I know people often say diversify your investments in domestic stocks, international stocks and bonds. What percentages should I be looking for? Should I be contributing more to my current employer Retirement account? Or should I attempt to contribute to my old Nationwide 457 OBRA-PST account? Also I notice in my Vanguard Brokerage acct that American Century still appears as the mutual fund... I thought the in-kind transfer would result in escaping American Century and utilizing a similar fund with Vanguard.. Any and all advice and suggestions are appreciated.
