@ninhalo5: You're welcome.

When you smooth, set the Magnitude value pretty high: 1500 to 2500 (Smoothing will also shrink the mesh so you can use it for sculpting, too. The buttock morph above was mostly done with the smoothing brush, not the deflate brush))
When you sculpt (shrink or inflate), set it very low: 0.030 to 0.100
When you move vertices around, set it slightly higher: 0.200 to 0.600

Dense meshes use more strenght than light meshes.
When the mesh crumples or turns "black", go back with the restore brush. (Set at low values)

It takes practise, but it gives you full control over your mesh.
