re: what should i do? (advice appreciated!)

Delay the SS until you reached the age for maximum monthly benefits.....see how long you can go on just the $1700/mo in pension payments. In fact, if you can get by on $1200 or $1500/mo, sock away the other cash. Don't touch the 401k or other retirement funds until absolutely necessary. Why? Cause you're gonna have insurance needs until 65, then you will still want to purchase Part B coverage to enhance your Medicare coverage. That stuff isn't cheap, and costs won't be going down.
