Have you read the docs in DOCS/tech/, especially encoding-tips.txt?
Granted, some are a bit out-of-date, but still worth reading. Searching
mplayer-users and mplayer-dev-eng archives will yield some interesting
results, too.

Oh and make sure you've read the HTML docs on MEncoder. They cover most
important options. The rest is manpage+expermentation, because there is no
best-quality-ever set of options.

Basically cropping the black bars and scaling to multiple-of-16 dimensions
is a good beginning, mbd=2 and trellis quantization are always a win. The
rest usually depends on source material (you may need some inverse
telecine filter for NTSC DVDs, for example).

To get rid of blockiness, yes. To get rid of grain or noise I'd recommend
denoising filter, like hqdn3d.

You mean post-processing? There are some pp filters, but they're not
necessary with DVD material usually (unless it's interlaced).
