Green Building Q&A: Does the blower door test result conflict with possible contractor recommendations?

My house is all electric except for a propane cooktop. I had a energy audit done last week. Although I don't have a proposal yet, closed cell insulation at the rim joists (fiberglass batts are there now), venting bathroom exhaust fans to the outside, and adding to the blown insulation in the ceiling (plus installing baffles) will probably be included. The attic area above the bedroom level of the house is not accessible now, so a hatch would need to be cut in a closet ceiling. My reading suggests this is a fairly typical approach. However, the blower door test gave a reading of 1145 CFM, which apparently suggests that the house is very tight. What would be the best approach?
