finehomebuilding, familyhandyman, and greenbuildingadvisor are all valuable resources with a different bent to each.
Counter-intuitively, air sealing is usually the #1 improvement. A good audit with thermal scans is worthwhile, especially if your muni offers a subsidized audit.
Tough to go into more detail without a little more information.

I think the hard thing for people to think about is that heat transfer is exponential. But we don't measure it that way. In fact R values are really misleading[1].
Meaning transfer coefficients can vary by orders of magnitude. So it's easy for one source like air leakage to totally swamp every other source.
[1] Figure of merit is really 1/R (smaller is better) not R.

Have a ~1800 square foot single family Colonial located in Northeast USA built around 1910. It was partially renovated ~2000 but most of it's still uninsulated (afaict, still very new to this!).
