So will that be enough to use as my only method of healing? Or will enemies be dealing as much damage as I will

Ahh, yeah. I was just getting it mixed up with the Vampire spell. If you're going to be putting lots of points into Healing, then it won't be as much of a disadvantage. You can't really use it as a sole source of healing, unless you're a lot faster than your enemy (you can sacrifice your damage for a greater chance to hit, I believe).
Enemies can deal as much damage as you, if not greater.

Well, it increases your sight range, opens up more perks and it may increase your chance to hit enemies. I'm not entirely sure on the latter.

The perks that increase attributes without saying you need 10 or under in that stat should be accessible whatever the amount of points you have. I don't know if temporary effects like you describe would have an effect on the perk system. I presume so, but in that case, you can either wait to regenerate health or use healing generally.

Some perks can only be chosen before or after a certain level (Inherited Resistance have a level cap for example and Slayer has a minimum level requirement). Other perks require another to be chosen first. This should be described in the manual and in the game's Readme file - which shows the more up-to-date info.

Some merchants like the one in the Crossroads region offer special items to the untainted and there may be other obscure effects, nothing crucial though.

I'm assuming that the perks that activate when you have low health will bring attributes above 10, otherwise I guess I just won't get them unless you know a reason for me to do otherwise.

The effect is only temporary, but it can help you to win battles occasionly. It depends on the kind of tactics you use I think.

I never bother to tag Diplomacy, there are some major enemies that can be persuaded out of combat, but I prefer bonuses to hit and damage from tagging weapon skills or a spell branch.
Barter can give you discounts or greater rewards occasionly. It may even effect a merchant's selling inventory.

And why does everyone say the Wielders are so good? The Inquisition looks better to me because of the +1 skill per level.

The Wielders route provides quite a lot of bonus Mana and an Intelligence upgrade (or two) leading to more skill pts per level.
Helping the Beggars does eventually lead to you acquiring a Luck potion which increases the attribute permanently. Another of these potions can be gained from killing the Goblin Khan. Those are the main ones, other than that, attribute increases come from factions or temporary effects.
