Yeah, 1 isn't bad, but won't really be any better than 10 and might be larger, since the encoder will usually only use 1 or 2 anyway.

DeathTheSheep has an old but still relevant guide going over different ways of achieving high-quality output, as well as going over the options with a more personal touch, so try searching for threads started by him.

If you're trying to hit a specific size bitrate is always the preferred option, which gives VBR too (CBR is actually very difficult to achieve, needs a lot of option tweaking). --crf is when you care about quality and mostly don't care about exact size. As compared to qp, it's when you want most of the video to be nearly as high quality as an equivalent qp but the size to be smaller (because some hi-motion parts are much higher quant and degraded). Certain options affect the tradeoff there, that thread goes over them.
