You got a buzz, you got a sibilance problem, you got a room echo problem.

Probably. Try putting some notch filters in at multiples of 60 Hz. Throw
in 60, 120, 180, and on up, and try adding and subtracting each one in
turn until you get as much noise reduction with as little change in the
voice. Boost the gain up a bit until it's peaking around -6 dB or so.
Consider a little upper midrange EQ to try and make the vocal less hissy.
I wouldn't try and do anything about the room problems. Downward expansion
might help, but you're apt to do as much harm as good.
