whoops, i just realized you were talking about 10NL and not 100 NL .

for 10 NL i think your guidelines are pretty solid. at that level, people just simply do not fold top pair. C-betting into two opponents with air is just asking for trouble against these opponents. However, as i said above there shouldnt be any hard and fast rules for your c-betting. At this level value betting strong hands is definitely the way to take advantage of their loose passive play. C-betting with air is often -EV against players who call too much. sorry if i confused you with my double post.
