You will also want to put full points in cooldown and power for rejuvenate. It's a very important heal skill. Unless you plan on going into combat a bunch, you only really need CD on your attack skills. Power doesn't add much damage, sadly. When you get into the upper levels, the damage it adds isn't terribly important. Also, clerics tend to be in a lot of parties after 60 either to aoe for experience or raid dungeons and instances. Therefore you tend to be healing more than attacking anyways. Adding to invincible like the others suggested is very helpful, for either invincing yourself or a party member. It comes in handy in aoe parties as well.

Later when you get the awaken skill, it is very nice to have full cooldown. It's an aoe heal that doesn't necessarily heal much, but the animation is very short and it has no cast time, unlike the other aoe heal. It really helps out in a pinch, although you have to be careful because awaken is a heal agro magnet. Also, it isn't necessary to add anything to the heal skills that heal a little over time. They help out a little bit, although the bulk of your healing is done with the other skills.
