OH AND I READ UR 5 SECOND RULE THING AND HOW DO I MAKE THE MACRO?
AND CAN U EXPLAIN IT EASYER?

If you intend to stick mostly to dungeons, you may want to stick slightly closer to an endgame build, but I'd still take some soloing talents just because it's unavoidable while you're leveling.  I've discussed IDS and CoH at length in other threads, so I won't bother to explain the merits and drawbacks of either build unless you have specific questions.

End Game IDS: With Holy Nova or Without Holy Nova
End Game CoH build: With Holy Reach
Leveling IDS Build: With SoL and MS
LOLSmite Build: With 5/5 FoW or With Focused Power

If you're going to do mostly dungeons, I'd suggest the Leveling IDS Build because it has some soloing talents (like Wand Specialization, SoL, MS) but it still has lots of healing talents.  If you are going to do any reasonable amount of soloing, I'd go with one of the LOLSmite builds, where the FoW version is more for leveling and the Focused Power build is more for End Game (not that LOLSmite is desirable at End Game).

As for professions, when leveling, money is more important.  I leveled with Enchanting and Tailoring, both of which are ultimately excellent professions for a Priest, but they were large money sinks, particularly Enchanting.  However, if you're willing to be patient, keeping your Tailoring ahead of your level will allow you to make some great pieces of gear while you're leveling and will let you make some top-notch gear when you reach 70.  Enchanting is similar, in that you can enchant your own gear to make it that much better and last that much longer.

If you're not for that, you can either pick up some gather professions for money now and then power level your profession choices later.  Some other professions to consider besides Enchanting and Tailoring are Alchemy (make your own mana pots), Jewelcrafting (make your own trinkets, rings, necks, and gems), and possibly Engineering (make some fun toys).

Finally, for gear, when you're in lower levels, focus on Int, Stam, and Spirit.  Most of the lower level items have that and those stats work fine for both DPS and Healing.  As you get higher, you'll start seeing +Healing, +Damage, Hit, Crit, and MP5.  This is when you'll start to need to make two different sets, one for healing, and one for soloing/DPS.  For Healing, focus on +Healing, Spirit, Int, MP5, Stam.  For DPS, focus on +Damage, Hit, Crit, Int, Spirit, MP5, Stam.

Hope that's helpful, let me know if you have other questions.

I assume you're refering to the stopcasting macro?

Type "/macro" (without quotes) into chat.  This will open the macro interface.
Create a new macro, and select an icon for it, and name it whatever you want.
For the body of the macro, type "/stopcasting" (without quotes).
Drag the macro to one of your bars.
Finally, select a hotkey for it that is convenient so that you can always press it at a moments notice.  It is pointless if you're clicking it.
