Hi Rusty,
Do you know if you have accumulated enough to sustain you through retirement ? Have you run the numbers through the FIRE Calc (there is a link to it on this board) ? Do you have a good asset allocation plan that you are comfortable with and that is appropriate for retirement ? What are you doing for health insurance ?
As others have said, you can roll your 401k into an IRA an take distributions before age 59.5 using the IRS Rule 72t. I am not qualified to explain it to you, but you can google it for information.
In terms of living off your assets, the rule of thumb is to use a 4% withdrawal rate (live off 4% of your assets annually, and adjust for inflation) and keep fund management costs as low as possible. I like Vanguard because of their large selection of low cost funds. (BTW, you almost certainly are being charged for fund maintenance -the information is buried in the prospectus).
I would suggest that before you make any moves, you study and ask questions. Also, if you are going to pay for financial advice, make sure you use a financial planner that you pay on an hourly basis as a consultant. The financial waters are filled with sharks that will be more than happy to take your money, and lots of it. Think about how much money 1% of your portfolio is on an annual basis (a typical fee charged by financial planners). If you are living off 4%, you are paying someone 25% of your gross income to do very little work. That's probably more than you will pay the government every year.
You've spent a life time accumulating this money, don't be rash. Read, study and ask. Make it your job to learn this stuff.

Much like this site, there are very knowledgeable posters there. Scam artists are eaten alive.
