I think witchhazel is great stuff. it sooths and has anti-bacterial properties and I always use it. Just don't get the store branded stuff its mostly water and or alcohol. At least get the dickinsons and the thayers is really great stuff.

As to stropping personally I strop 60x before shaving and never after. I did an experiment awhile back which you can read about in the help files and it was in the stropping area under the grand experiment. I found no difference in before and after stropping but hey its all about finding your own way in this thing.

I can't help you with the moustache area as I have a full moustache.
