Welcome from one public employee to another!
It's never too late to begin saving. Your plan sounds good to me. I have several friends that work for elected officials and when an election happens, their jobs are at risk. All you can do is to put away as much as possible, which it sounds like you're already doing.
Even if you don't reach the magic number by 2011, you could still keep putting away money until you have enough (maybe a couple more years), instead of sticking it all the way out to "normal" retirement age. No?
Does your pension program have a health insurance component? Mine doesn't, but I think they still offer it for people hired before 1989. I don't know a lot about health insurance, but if you intend on moving overseas, where health care is cheaper, I think a lot of people just self-insure for minor issues and buy a high-deductible, catastrophe plan.
