a) As one of the authors, yes.
b) Both (see below)
c) yes

I agree that we should proceed on the basis of specifying FROST. However,
most of the work that went into my spec was setting up the text so it is a
logical extension of RFC8032 and producing test vectors. So I think it
would probably make sense to merge.

I would also like to ask why we are starting with the hard application
(signature) and ignoring threshold key generation and threshold key
exchange.

On the NIST topic, I am pretty sure they don't want us to be waiting on
them.
