For now I would assume just make sure you have TP into holy strike and enhanced armor. Other than that I don't think it really matters until later on when you have elites etc. Early game is all about making sure you have enough damage to quest easily. That's about it.
for the rogue side obviously shadowstab, lowblow, hide. Whatever passives you want to put tp into. After lvl 50 a lot of your skills cap out so its easier to choose. Rogue has a lot of really nice skills.
