Allocate your talents as best suits your personal style. If you cast Renew often, you'll definitely want Improved Renew and Empowered Renew. If you seldom cast Renew, spend your talent points elsewhere. If you're a Holy priest who won't be using Power Word: Shield often, do not spend points on Body and Soul. It will consume your energy, and can't help you of your wow gold farming. Wow gold is the in-game money; you can use to buy weapons and items and so on.

 

The big bread and butter spells for Discipline priests are Power Word: Shield and Penance. Power Word Shield mitigates incoming damage and is a fast cast spell, so Improved PW: Shield is a given. Penance is a powerhouse healing spell. Couple this talent with Aspiration, which reduces your Penance cool down. These two talents, together with Glyph of Penance, make Penance an extremely powerful spell and the Discipline priest who wields it a powerful single target healer. You can take with the two to help you farm wow gold. Even with the nerf scheduled for 3.2, every Discipline priest will want this spell in his or her arsenal. Other talents the Discipline priest will find very attractive are Divine Aegis, Borrowed Time, Grace, Pain Suppression and Rapture.

 

The other primary spells you will use as a Discipline priest are Prayer of Mending and Flash Heal. You'll be pre-stacking PW: S and PoM on the tank every chance you get including wow gold. You can use these two spells, along with Prayer of Healing to help out when a large amount of raid damage comes in as well.
