Firstly, restoration is not necessarily essential, but it's that bloody handy that it's more than worth putting points into. Especially with some other perks that increase magicka regen or give you stamina as well as health in your healing spells.
Don't underestimate conjuration. If you don't want to invest in offensive magic at all, fine, it'll work fine anyway, but sometimes a conjurable creature is great for, if nothing else, drawing attention.
Keep a spare weapon on hand. There are some draugr who use disarming shouts, and in a battle, it can be pretty hard to find the weapon again.
Remember when choosing to use two handed or one handed weapons that blocking with a shield is more effective than blocking with a weapon, even if said weapon is two handed. So it depends how offensive/defensive you want to go.
Before you do anything else, I'd recommend striving to get the complete fus-ro-dah shout. It's really handy in tough situations. Just follow the main quest until you get it, you'll know when. Then, if you feel like it, leave the main quest altogether.
Bows are handy for getting your stealth up if you're not very good at stealth in general. You don't have to get so close to land a stealth attack.
Make a good amount of saves per character. Even now, skyrim can be rather prone to bugs.
Aside from that, go nuts. There's no build that full on just doesn't work.
