Good PVE group make up

Through the wonders of RAF i am going to make a 4SP/1Prot Pally group. Planning on using a 70 to grind the priests to 40-45 in instances and just promote up the paladin. Afterwards i was going to start working on macros and what not for the best way to keep aggro. I was thinking the SP so that Vamp embraces and Mind flay should keep everyone topped off, baring a bunch of crits. If anyone has any suggestions let me know. As to race i'm thinking human cause of the new SP talent that increases your shadow damage by amount of spirit.
