Where the 4473 asks if you have ever been convicted of a felony, I think you still have to answer "yes," but perhaps one of the members here who is an FFL can read the instructions for that question and verify that.
Nope. If you answer yes to that question, you will not be sold a firearm, period. From the rules for 4473:
EXCEPTION to 11.c, and 11.i.: A person who has been convicted of a
felony, or any other crime, for which the judge could have imprisoned the
person for more than one year, or who has been convicted of a misdemeanor
crime of domestic violence, not prohibited from purchasing, receiving, or
possessing a firearm if: (1) under the law of the jurisdiction where the
conviction occurred, the person has been pardoned, the conviction has been
expunged or aside, or the person has had their civil rights (the right to vote,
sit on a jury, and hold public office) taken away and later restored AND (2)
the person is not prohibited by the law of the jurisdiction where the conviction
occurred from receiving or possessing firearms. Persons subject to this
exception should answer "no" to 11.c. or 11.i., as applicable.
