You could cut back your phlox now, but I don't know that it would do anything to increasing your phlox next year.

I do know my MIL stuck a peice of phlox into the ground and it rooted and grew for her, which follows Kathy's suggestions.

Myself, I always use division. It takes a year to two for the plants to increase in size. I have never had to use support rings for my phlox plants either - they tend to be sturdy plants, however there is no reason you cannot put support rings around them if you would like. I have offered up phlox seed in trades, however I question whether the plants from the seeds would grow true to the mother plant.
