Also, if it helps, the concept of my character is a young (chaotic good) wizard, that begins his travels to develop his skills. Not an evil necromancer thats gonna raise legions of undead, i was thinking of a classic mix of Gadalf/Dumbledore type, the strong and silent type of wizard.
#2: Dumbledore implies a more bookish mage concept IMHO; I'd suggest going more Gandalf-esque to get the whole 'adventuring wizard' sort of feel, unless you're not looking for that.
#3: Dual specialization offers some decent benefits; and if you're looking to do a single-school mage, look into the Renegade Red Wozard theme, which offers benefits in place of the secondary school.
That said, if you're looking at things like the Focused Specialist PrC, or some of the Unearthed Arcana alternate class features, then it might go somewhere.

(Or Mithrandir, or Olórin, or Incánus, or Tharkûn, or Greyhame, or Stormcrow, or Láthspell, Greycloak, or The White Rider, Sharkún, Khuzdul, or Grêg-Hama, Cáno, Forlong or Fornold or...)
Specialization's main benefit is that it allows you to cast an extra spell from your chosen school. So.. if you want to a transmuter, for instance, you could do that more times per day... at the expense of not being able to cast spells from a certain school.
Unless you want your character concept to focus on a certain type of spell, it's generally better to be a general wizard. If you want to cast the same spell many times in a day, there's always the option of scribing a scroll or two.
You could go through the movies and try to find DnD equivalents to the spells and abilities these wizards use. If you can do it while specializing, then go that route. If you feel later that you need more variety, ask your DM if your wizard can make some unique spells. If specializing doesn't offer you the spell choices you want... go generalist.
Just a recommendation.
If you haven't played a wizard before I recomend not specializing. Optimization wise its not quite as good. Its also more restrictive.
You give up schools of magic, which is giving up options. Options are why wizards are good.
If you are interested in specializing, consider doing it for your second or third wizard. Take note of the schools of magic you tend to cast, and which ones you don't. Then in the future specizlize.

According to this person:
people normally should specialize because there are spells that they're just not going to use a lot
the best schools to ban are Evocation + either Illusion or Enchantment
and the best to specialize in are
Very good: Conjuration, Transmutation
Kinda: Abjuration, Divination, Necromancy, Enchantment
"Friends don't let friends specialize in Evocation" -Internet
EDIT: if your wizard is in a party with a rogue, I do not recommend dropping illusion. Normally, if a rogue wants to do game-breaking Sneak Attack damage, he and a partner need to be exactly opposite each other for flanking a common enemy, making him dependant on the enemy not moving out of the way. If the rogue is invisible, however, he does not need a partner to deal SA damage, so he is less dependant on an enemy standing still.
Therefore, a wizard in a party with a rogue would probably not want to ban the ability to cast Invisibility on said rogue, making "Evocation + Enchantment" better in this case than banning Illusion (especially given what is said in a later post about entire categories of monsters being immune to Enchantment due to not being intelligent enough).
Specializing in evocation can be awesome with the right feats and classes.
As for barring Evocation, there's really nothing that it can do that some other school can't do...especially since there's shadow evocation. All it takes is some way to tank their Will save (mind fog?) and they're getting blasted by a 'fireball' (or your evocation spell of choice). The fact that a lot of Evocation spells are based in energy damage (and there are quite a few critters out there that resist the types) doesn't help it any.
@Beldak_Serpenthelm - I'd shy away from barring Illusion if you're also dropping Evocation...it cuts out some of your damaging potential if needed. It also hurts your control aspect, since it has quite a few ability-damaging spells (phantasmal assailants (8 Wis/8 Dex at level 3), shadow spray (4 Str in an area at level 3), etc.). I don't know what to cut, honestly...probably enchantment (even though it drops sleep and other control spells).
I really don't like shadow evocation as a substitute because it allows them two saves instead of one, and there are those "60% real" caveats that just ruin it. Sure, you can try and drop their saves, but it's still an extra save, less damage, lower level spells, and mind-affecting. There's just too many things that can go be used to shut it down.
If you want a "balanced specialist" I would recommend specializing in conjuration and dropping evo and illusion. Conjuration has decent cc, unique efefcts, and damage. Enchantment has the best and hardest to stop mental effects. Necromancy has good save or dies and works against undead well. Can't drop divination. Transmutation should never be dropped. Ever.
Depends on the party build, in my opinion. If your party is loaded with damage, take something that'll help control the battlefield; if it's control-oriented, take some damage.

Definitely enchantment. There are huge swaths of creature types (undead, vermin, plant, construct, probably others) that simply ignore all enchantment spells, because they are by definition mind-affecting.
