vobsub support should be possible - it's the same codec as DVD subtitles. 
srt doesn't have a codec yet, and will require some architecture changes 
as ffmpeg currently only supports bitmapped subtitles, not text-based 
ones. As always, patches welcome!

No idea about that, I'm afraid!

If you can make a short sample with vobsub subtitles I can probably knock 
up a patch to support it.
