come to think of it, as a one man band, what is your preferred order of recording instruments? i know it would depend on the song, but if i had to guess i'd say you first record drums, bass and keys for a backing track, then vocals, and then the extra stuff that fills in the spaces like guitar or more keys and vocal harmonies
first supertemp perc, then supertemp rhyth/chords, just to have something to sing over. then temp voc. then better instruments. then better vocal. and around we go
