Yup. What he said. One thing though. I'm pretty sure it's abjuration that affects healing and buffs. Alteration is for dots, roots, and debuff type stuff.
And I want to reinforce one more thing, because it's something people get confused on all the time.
By "specializing" in one skill type or another, that does not mean you just train in that specialize skill. You should (and in fact must) put a training point in all 5. What we call your specialization is the one skill that exceeds 50. That could be any of the 5. How it's determined is that the first specialize skill that hits 51 becomes your specialization. The remaining 4 skills are then capped at 50.
But you still have a specialization skill for all 5, and even at 50 points it still provides a benefit. So there is no reason not to put points in all 5. In fact, if you don't have at least one point in all 5 skills, then none of them can actually hit 51 (this is a bad thing). We get posts all the time on this board about someone complaining because their specialization skill never seems to go past 50. It always turns out that they just put points in the one skill and ignored the rest.
What you want to do is this. Pick your specialization first. When you hit 30th level and have some free time, go to your class guildmaster and train one point in all 5 skills. Then find a nice quiet place and cast the cheapest spell of the type you want to have as your specialization over and over until it hits 51. At that point, you are done. Go out and adventure normally. Your various skill will increase gradually with use, but since you've already locked your specialiation, you don't have to worry about which spells you cast (don't want to accidentally hit 51 with the wrong skill first).
For wis casters, since you get specialization at level 30, you will start at a skill level of 30 when you first train it, so it shouldn't take too long to get just those 20 points.
