Seal gaps and insulate first. Close that flue vent (top and bottom) if
you're not going to use it.

Since you already have woodworking skills, I'll suggest building solar
air-heating panels for the south (first) and west (second) sides of
your garage. The panels on the west side will need plywood covers
during the warm season, but will gather warmth during winter
afternoons.

If you need help getting started, you're invited to visit next time
you're in the Des Moines area. It might also be helpful to lurk on
news:alt.solar.thermal - there are a few people there who really know
their stuff (as well as a fair number who just like to dream). If you
lurk for a while, you can probably sort 'em out for yourself. :-)
