Income earned while drawing SS, not pensions, can count against you. I just re-ran the numbers from drawing at 64 and 66 up to age 70, and I'd pull in more money drawing earlier up to that age (70). I heard the radio financial planner Ric Edelman once talk about how you can get very, very screwed by the IRS when pulling money from your IRA/401K if you miscalculate your expect number of years between retirement and when you kick the bucket. IIRC, he gave an example where the penalties can be over 100% of what you draw in a given year.
