Awesome, good feedback all around. Let's see...

As for a baby priest you might consider Holy. Dics is very nice (I much rather heal with this spec) and mana conservative but it's juicy healing talents are lower down in the tree. I'd do some holy at the start and then go for disc a bit later on if you felt like it. Experiment a little and have fun!
Stats that you will want are Intel and Spirit for sure, but don't leave out stamina too much. As to what stat you want to stack I personally would go with what felt right at the time. Finding a balance is fairly easy. The lower levels are pretty forgiving on that angle.
As to healing mods I personally like HealBot. A lot of people swear by Grid too. I tried Grid and it was too damn colorful and configuring it was clunky to me so I went back to Healbot and am still satisfied with it. You can use the basic UI to heal with but it begins to become uncomfortable later on (around 65 for me) when you have more spells and more things going on with the group. I hear a lot of people use mouse over macros to heal with too. Just like a HealBot but you have to add in a lot of macros (and keybinds?) as far as I can tell. The standard UI is fine if you are a purest with that sort of thing but it does lack a certain level of awareness that a mod can give you. If you do decide you want a mod later on after you get your first few healing spells and know kinda how to use them head on over to Curse and browse the add-ons for healing. Pick a few at a time to work with and don't be afraid to dump something if it feels too clumsy. The thing here is to find what you like to look at. How does it feel to use? Are the controls and configuration interesting or confusing?
Early on game play should be fun for you. If you don't like the priest play style then try out another class. Some people might give suggestions, take those with a grain of salt because what works for some might not work for you. Don't worry too much about the roll you will want to fill at end game, ideas change as you level. Basically just have fun learning, take it easy and always remember...people WILL die and some may even blame you for it and most importantly...Ignore the jerks!
SUPER helpful, Tyga! I'm definitely willing to play with both the Disc and Holy trees, I just had no idea where to start. Since I've never healed I didn't really know the difference between the two, lol.
I've used Grid in the past (when I tried to switch hybrid classes over to healing) and it was quite colorful. I'll give a few others a shot. I've heard of addons that let you do mouseover healing too, but that'll take a bit of research on my part since I'm not very macro-savvy
And I'm starting with a priest for a reason. I've gotten a lot of people telling me druid is easiest, but I already have a mid-twenties druid on the Nesingwary server. I'd rather not delete her if I can avoid it, but it comes down to the same problem as before--switching over is not easy for me. So, a priest, from the beginning! I'll give it a shot though, and if I don't like how it goes, I'll try something else.

One addon you should look into, other than Healbot, is XPerl. It will alter the unitframes to show incoming damage and healing, and overall make you a much faster healer. Another good addon is DrDamage. It's a theorycrafting addon that calculates the damage, and healing, of your spells. It's really helpful in learning which spell heals for what so you know when to use that particular one.
Ooh, DrDamage sounds useful. That's certainly one of the things I need to learn, what spells to use where and how to not OVERheal

Holy: The most traditional healer class/spec in WoW. Able to cope with anything, but needs to be well fed with mana. Take drinks!
For levelling, either is good.
I would suggest if you plan to do ANY solo content/questing that you dip into shadow for Soul Tap.
Thanks for the breakdown, very helpful

I'll also keep in mind that Shadow tip. I definitely want to level this guy mostly by dungeons, but some days I might just not feel like it, and having some extra edge would be nice.

I looooooove healbot, in fact it's gotten to the point that I miss it when I'm not on my healers, so I have to create a dps version now. Also, someone recommended binding misdirect to healbot on the hunter, so that when you, say, left-click a portrait you'll MD to that person. Nifty, no?

Haha, I love that misdirect idea

I'll have to give Healbot a shot (if it works). I know I tried downloading it before, but for some reason it wouldn't show up...it was very odd O_o. But that was also like a year ago, so maybe updates since then will make it easier to use. XD
