If the brake track doesn't have a deep groove in it, i'd just clean it up with an emery cloth pad, and throw some new bearings in. Should be <$30 and about 15min work.
If the rims are very worn, you could order some Kinlin 31 rims and swap them onto your current hubs & spokes, pretty sure the ERD is close enough with the Flo 30s to work without recutting spokes.
