Well, I've been looking through the Paladin skill tree and it looks like for the most part it separates into two distinct trees of Magical attacks and Tanking, with a neutral tree in the middle having some Physical attacks. I know with any class it is generally a good idea to dabble in each area a little and pick one side to specialize in. For the most part I think I might get Sacred Hammering and just focus in on the Tanking and Physical attacks, going for Guardian eventually.
