To reduce the noise, keep your samples at ~50 as you have it, but check the "Square samples" box. It will reduce/eliminate the noise, but take quite a bit longer.(If you are rendering on CPU then probably set the tile size to 16, as it generally produces faster results)
If you are getting various flecks that are not the normal noise (blue ones, or whatever from maybe a really shiny material or volumetrics) you should set "clamp indirect" up higher (usually to around 3 works for me)
