Just a hint, blacksmithing is good but it's best to perk the right (heavy) side of blacksmithing even if you are light armor. Why? Because no matter what path, you can make light dragon armor at 100 smithing perk, and if you go down the heavy path, you also get Deadra, which is heavy armor but the weapons can be used by anyone.
In other words, go through heavy side of smithing and you get Deadra weapons (best weapons in the game) along with light or heavy Dragonscale armor at max. It's the best of both worlds.
Just thought I'd throw that out there.
