Your photos show filiform corrosion. Seat tube looks relatively free of rust, if some of the brown is grease as I suspect.
I'll leave evaluation of the seat tube cinch area to more those more learned in frame building.
(I will note, however, that closeups of corrosion gives me the willies; rather too much like looking too close in the mirror in the morning, or using one of those magnifying mirrors... Ack.)
