The College of Winterhold is where you want to go for training. And you can get some good spell tomes from the mage in Dragonreach in Whiterun.
In the end, if you don't find a build that is fun for you then it just might not fit your playstyle.
I'm currently playing a heavy armor conjurer that fights along with my summons with destruction. I also use alteration for extra AR buff with flesh spells. Sometimes I use bound swords, but usually destruction. When I encounter an enemy I first bring out the Atronach (Frost one right now) and then Flame away. This usually uses a lot of my magicka so I might have to use some potions until I get some Conjuration reduction gear.

i had the impression you couldnt do that before..maybe they changed that.
turtling behind the shield and breaking cover to give a nice zap.
Didn't use conjuration and archery myself, I might try that in the future.
