questions on IRS sales

Have these questions about IRS sales: Will a Deed from the IRS wipe out municipal taxes due? If both municipal taxes are due and the IRS has a lien, which would be subordinate? Can bankruptcy protect you from an IRS sale? If a property is sold at IRS sale than the amount the IRS is owed, does the owner have a right to claim the excess, as in Sheriff’s sale, in my state (NJ)? Anyone with expertise in this area…I would appreciate your hepl. Thanks
