1) Yes, I will. Unless I break the law to the degree of a felony while in government service. If I leave and, years later, do something, it doesn't matter. There's a bill pending in Congress to expand the rules concerning denial of Congressional pensions. from the article I just read, only treason and a few other crimes can cause a legislooter to lose his/her pension.

2) I was a bit wrong about the calculations. Billthekid was on the right track. Congressional members and Congressional employees get 1.7% per year of Congressional service (not to exceed 20) PLUS 1% per year of other government service. Just as an FYI, Air Traffic Controllers, Firefighters, Law Enforcement Officers, Capitol Police, Supreme Court Police, or Nuclear Materials Couriers get 1.7% per year up to 20 years and 1% per year after that.
