Welcome anyeone410!
I have quite a few Dens 'cause I love 'em, but I don't purport myself to be an expert. That said, if your Den is flowering and you disturb it, the buds will likely blast (die). As far as the roots on the keikis go, I would wait until they grow just another inch or two longer before separating them for re-potting. It cant hurt to be patient. I'm waiting on a cane-top keiki myself. When you do separate them, a sharp (sterilized by flame) Exacto knife, a pair of pruning snips or Bonsai scissors will cut them off quite nicely. Some people pinch them off by hand, but having the right tool for the hobby is always the best way to go.
