A command squad comes with an apothocary as the leader (kinda like a seargent) so the points are built in. I don't know the points for Sanguinary Priests but they are from a different book, so unless you want to play Blood Angels you can't use them.

I wouldn't actually suggest giving them special rules or anything, Just paint one guy up like an apothecary per squad, unless you really wanted them for their 4th ed special rule rather than appearance.
