I can dive dry with less weight than diving wet, as the buoyant neoprene is no longer present with my Tri-lam dry suit. Be sure you are burping the suit before entering the water and add only enough air to keep you warm.
PADI teaches to use the suit air to control buoyancy and not the BC and I follow this practice because it works for me. This appears someone controversial as others manage with their BC. I find it easier to control buoyancy in one place vs. two.
Be sure you're managing however you're controlling your buoyancy consistently. I've never had an issue using my suit to maintain buoyancy and rolling my shoulder should I get too light to let some air out.
As stated above. Don't get too frisky without some time with an instructor in the water.
ETA: I don't have the link handy, but @rsingler buoyancy spreadsheet may help you estimate your weight requirements.
