My personal recipe:

Confidence .9
Variance 1/64
Samples to taste, for quicker renders, 10 does the job. For final 
renders I'll go as high as 1000.

Why 1/64 on variance? Well, pixel-to-pixel it's very hard to see the 
difference between a value that's 4 levels different than the next 
(Though 3.7's gamma may change that in shadow or highlight areas) If you 
must, go for the default variance. It slows a little bit, but not much. 
As for confidence? Dunno. .9 is just sort of an arbitrary value.

Either than or start with the defaults, They're good enough (except 
samples) occasionally I'll push confidence to 3 nines or even 4 nines, 
if I think I'm going to get anything out of it.
