Well my main char is basicly what you are describeing, more or less.
Kajjit Spellsword
Main Skills:
Blade
Block
Heavy Armor (best protection)
Destruction
Alteration (The shield spell ads a % of your current ac to your total ac, Get 30% sheild and good armor and you can take a s**t load of punishment

)
Restoration (Restore health, better than gulping potions the whole time)
Illusion (Just in case things start to go wrong or if you need that all important first blow)
Starsighn The Lady +10 Will power +10 Endurance ( Boosts HP and Mana Ragen. time)
Well thats my char, But he's more combat oriantated than the one you described. I like to go in swinging and use spells to heal and protect.
Hope it helped!
