hg qcommit and hg qfinish are only for adding the patch to your local tree, and probably don't want to do them.

For me:

$ hg qnew Bug####
( I do set a guard on the patch, I can explain guards later if you want! )
COED!
$ hg add <any files added>
$ hg rm <any files deleted>
$ hg qrefresh
go back to "COED!" till everything works

$ hg export qtip > ~/the.patch
( then I upload the.patch to zilla! )

To update:
( after making sure I've done a qrefresh )
$ hg qpop -a
$ cv -u
( cv is my cvsreport alias )
$ hg qpush -a
( this will push everything, you can do 'hg qpush Bug####' if you just want that )

Once it's committed:
( insert first 2 steps of updating here )
$ hg qrm Bug####
