I would add Spray Foam to your list. Increases racking strength of walls, provides an airtight seal and vapor barrier (2lb- Closed Cell Foam), and will eventually pay for itself in Heating and Cooling savings. We have a a very large cottage in Northern Ontario (3000 sq/ft +) that has been sprayed foamed (Demilic Heatlok) and has in floor radiant heating and forced air AC all supplied by Geo Thermal. The electric bills a year are less than what some people spend at Starbucks. The comfort is incredible in -30F/-34c or +100f/38c and a bomb could go off outside and I doubt you would hear it. The costs to insulate the whole house and to install the Geothermal (including AC) was 55k, less than what some folks spend on kitchen cabinets and counter tops.
