You seem pretty well on track. Look into getting perlick faucets though since they are forward sealing and work wonderfully in a seldom used environment. Also get a faucet wrench to help you take it all apart to clean.
3/16" line is preferred because you will need less to get the same pressure drop (you want barely any PSI at the tap) so plan on 8-10 ft of 3/16" line for each tap, plus tube for gas as well ( either size or bigger works for the Co2 side)
