No, it doesn't.  You can just grab the ebuild file and use it locally.

Smaller will generally mean worse looking and longer encoding time.

You don't need ffmpeg.  You just need "mv":

 mv foo.m4v foo.mp4

If you mean you want the files encoded at a resolution of 1024x600,
you can tell handbrake what output resolution you want.  You'll get
far better results by encoding to the desired resolution, format and
bit-rate you want the first time than you will re-encoding a second
time.

You can create your own presets with whatever encoding settings you
want.
