<human>: Can you give me the gist of the text in a nutshell?

I'm now a self employed translator 30 years old and fill out a 1040 for taxes and make between 30 and 50k a year. No debt and though I plan to rent a cheap apartment next year my only big expense at the moment is 170$ month for health insurance. (Affordable, yeah right)

I have 29k in my old employers 401k with 38% in large and small us equity and 23% in international with an average rate of return of 9.28% (principal financial group) 

I also have 45k in a savings account doing nothing which is really which brought me here. I'm not sure what to do with that money and have no clue about what I can do in terms of IRA, 401k, taxes, deductions, etc to lower my taxes and increase money coming my way.

Should I invest it? Can I invest some to lower my income and thus taxes? Any way to lower self employment tax?
<bot>: what to do with 45k savings and 29k 401k to maximise money for a self employed goon like me?
