Those Italeri Indians are very nice, will have to get hold of some to supplement the Tecumseh set when it comes out.
Other sets useful as various US regulars are the HaT "Waterloo Netherlands Militia and Belgian Infantry" and Emhar "Portuguese Infantry and Cazadores". Both have tunics with no lace and the latter have short gaiters reminiscent of the winter gaiter-overalls sometimes worn.
