I strongly advice Maintankadin site - it's been on internet since like... forever. There you have complete information about Paladins mechanics.
About rotation - its famous 96969 where you rotate 9 sec. cd's (Consecration, Judgement, Holy Shield) with 6sec. cd's (HotR, ShoR). Note that 2 out of 3 nine sec cd's are not really 9s, but for sake of rotation and maximising dps you pretend they are.
