You present an interesting question based on the facts you present. In this day and age, it is rare for people to retire before age 65 due to health care costs but you are looking to retire at age 58. I hope the early retirement stems from your choice rather than an external necessity such as job loss or medical condition.
Additionally, I'm going to read into your question a little further and make the assumption that all of your retirement savings is in the 401k plan. While $266,000 is nothing to sneeze at, it is not sufficient on its own to cover your retirement needs.
If I were in your shoes, I would resolve the debt issues first, second I would focus on retirement planning, and only then would I make decisions on the investments. At the risk of sounding self-serving, I'd suggest talking to a financial advisor and or attorney offline to get guidance on your specific situation.
A couple of points to remember about 401k plans are that as an employer-sponsored qualified plan under ERISA, a qualified plan has a very high level of creditor protection and also that a 401k plan can sometimes be drawn on after age 55 without a 10% early withdrawal penalty and also without leaving your employer.
I'll be interested to hear what the other advisors have to say.
