the q-value does not determine the size, but the algorithms used in mp3
encoding, where q=0 means best, but very slow and q=9 means fast encoding and
poor quality. q=2 seems quite useful and is recommendet (look at lame-manpage
for details)
what you are looking for is the -V n   0 <= n <= 9 switch, which does
determine the file size.
i know this problem, i once mixed up these two switches myself ;)

man lame: --comp arg
              Instead  of  choosing  bitrate,  using this option,
              user can choose compression ratio to achieve.

not sure about this: normal uncompressed audio (a.k.a. .wav)

don't know exactly about all the other questions, sorry.
