Some thoughts.
The pension is probably the better deal compared to the lump sum. Why? The discounted interest rates have increased in the last two years, decreasing drastically your lump sum. Also, depending upon your bills, your Social Security is something you need to evaluate in order to ascertain when to take it. Many folks advocate 70 but for many, this is not financially viable, since they need the cash flow now, or in the near future. Those who have a Traditional IRA can convert to a Roth, but it is important to understand the tax implications. The best investment you can do in this arena is to contact a tax accountant (not H&R Block), but a tax CPA or an Enrolled Agent for a review. Yes, they will charge for the evaluation, but the planning will save you thousands in the long-run. A good time to convert is when your tax rate is low, say in the 10, 12% tax rate A spread-out of the conversion is usually recommended over a number of years to reduce the tax.
After seeing your tax accountant, depending upon your financial knowledge, I would recommend a financial advisor at least for a preliminary look. During retirement planning sessions, names from other participants of advisors can be obtained. Any way, good luck. If you are financially astute, a self-directed IRA is something to consider. And as many folks have stated, the medical insurance is the real stickler before 65. If you have it through Ford, great. If not, this can be what may preclude you from retirement or at least your "vision" of what retirement is about.
