I'm lv69 almost 70 now what skills should I lv up 1st?

Okay. I do wish that you gave a little more detail, but let me try to answer this as best I can in a broad sweep.

Healwise:

Ironheart: Max it
Wellspring: Level/Max it. (It can wait.)
Stream of Rejuvenation: Level it some. (Not much yet.)
Chromatic Healing Beam: Level it some. (Enough to be efficient when you do need to use it.)
Blue Bubble (Regeneration Aura.): You MUST have this.
Blessings of the Purehearted: Leave it alone. I use this skill and wellspring as chi chargers. (Wellspring due to its speed, and low mana cost.)

Buffs: Max them all. Get the AOE buffs.

Attacks:

Plume Shot: Max it.
Great Cyclone: Max it.
Wield Thunder: I'm working on maxing it, because it is your best non chi nuke, so I'd say max it.
Siren's Kiss: Depends on how often you use it. If not often, save it for later.
Thunderball: Mines is level 1, but I have seen some people actually use this skill effectively. I say that if you know how to use it effectively, max it. If not...leave it at level one.
Razor feathers: You don't AOE grind, so you can leave this for later. I will point out though that this is your hardest hitting physical attack. Just make sure other mobs are out of its attack radius if you do plan to use it for one on one. I personally have this skill at level 7, but this is one that can be maxed later.
TEMPEST: My favorite move. You should at least get this skill. Personally, I'm working on maxing mines. Yet it costs a ton of spirit to max, so its up to you. Nonetheless. This is your hardest hitting move, bar none.

Debuffs: I personsally would tell you to save them for later. However, if you do level them, and use them effectively, your party will love you for it. I do recommend that you have each of them. Mines are low leveled, but even so, it does help when I use them, and I can use them pretty effectively too.

Miscellaneous:

Metal Mastery: Worth maxing. Your attacks will be 20% stronger with this on. (Also makes your metal attacks at least decent if you accidentially use them when fighting metal mobs).

Red Bubble (Heaven's Wrath): Honestly, I have not had to use this yet. Nonertheless, I recommend that you have it. Better to have it and not need it, than need it and not have it. It only has one level, so get it.

Plume Shell: Learn to use this effectively, and it will save your life. I've even taken a few direct hits from wyvern biting on my cleric and lived to tell about it. (Aggro ping pong isn't fun...especially when one dies, and the other can't take the aggro). This skill will save you. Especially in a party when you take aggro by accident. You see the mob coming at you...intent on destroying your friendly little cleric. The mob is physical. You realize you can't take too many hits from it. Throw up plume shell to greatly reduce the damage taken. Ih yourself a few times. (People tend to notice when the heals stop coming...especially if you normally heal them effectively.) This gives time enough either the tank or a DD'er to grab the aggro from you. That way you can prioritze on healing. If no one realizes it, then its enough time for you to type the words "Help" in chat. Run to the tank so that they can grab aggro, or run to another DD'er so that they can. Then heal liberally. In short, MAX this skill.

Purify: Level it at least decently by level the time of your fb69.

Revive: Max it as your level increases, and you begin to do more squadplay, bh's,fb's, etc.

Level 79 buffs, and lvl 100 buffs only have one level, so they are worth getting as well.

Hopefully this helps to answer your questions some, as well as help anyone who has similiar questions about it. Feel free to ask if you have any more questions. I'll do my best to answer them as best I can.
