The exhaustive list, not prioritized brain dumping
Exterior:
Front Porch

Electrical: first phase (single fixture/existing wiring)
Electrical: second phase (additional fixtures/new wiring)
Exterior siding/rockwork
Windows

Front stair (sideways)</p>
Roof
This is most likely a tear-off and rebuild. Researching materials, properties, styles.
Chimney
Necessary repairs, extension if new roof, flue liner, possible refinish
Front sidewalk
Replacing the broken sections, adding cable routing underneath, adding french drain. Possibly paver or fieldstone
Side sidewalk
Repair/Replace existing frost-heaved walk, add drainage
Retaining wall
Add front-side retaining wall
Rear concrete
Rip out
Garage
Build new
Patio
Build new, same time as garage pour
Siding
Get rid of crap aluminum, re-do with something else. Researching materials, cost, etc. Vinyl is looking like the big winner. Also
Insulation
Finding a good solution to insulating an old house is a right bitch. Ideal time would be during the re-siding phase, probably with isocyanene pumped in.
Windows
Tough call here. I love the old oak-frame windows, but new glass would be more energy-efficient. Reglazing the existing windows is an option, but a time-consuming one.
