of course:
crop[=w:h:x:y] (e.g. crop=720:432:0:72 - take 432 pixels from the
middle, crops away a 72 pixel bar up/down).
output of cropdetect is quite useful for this.

yes (-npp li iirc, some other stuff check manpage/docs).

i remember having seen some postings on the mailing list about this issue,
iirc there is a normalize-plugin (volnorm), but it only works for mplayer, 
not mencoder (as all audio plugins).

btw most of this is in the docs/manpage/mailinglistarchive :)
