In my experiments, I've found that a high value (greater than 2.5) of Initial Final Gather Density will increase your detail while introducing noise (I think it's trying to increase the detail in the surface of the texture and gets carried away).
I usually use a value of 3.

Use a bit of Interpolation to reduce any noise (Interpolate Over Num Final Gather Points). Higher values of Interpolate Over Num Final Gather Points do not add a lot of overhead to your render times and it tends to smooth out noise. Downside: it removes local detail.
1=very blotchy; 30= pretty good; 200=Very Smooth

Hope this helps.
I usually use 30 for test renders and 100 for renders towards the end of the project.
