I'm most experienced as a DK tank, so in case you choose to go down that path, I'll gladly provide tips for it:

For lvling, I used s&b/resto in all heavy. I wore 5pc Hist Bark/3-4pc seducer/random arcane-enchanted jewelry pieces (random jewelry until I could get to v14 where I'd have much better gear). I focused quite a bit into both magicka and health, with a little into stam. Now that my DK is v14, I'm successfully using the following setup:

Sabatons - v14 - Seducer - Reinforced - Magicka
Girdle - v13 - Footman - Exploration - Health
Cuirass - v14 - Seducer - Reinforced - Health
Helm - v14 - Seducer - Reinforced - Stam
Pauldrons - v14 - Seducer - Reinforced - Magicka
Gauntlets - v13 - Footman - Divines - Magicka
Greaves - v14 - Seducer - Reinforced - Magicka
Mace - v14 - Hist Bark - Defending - Disease
Shield - v14 - Hist Bark - Reinforced - Stam
Resto - v14 - Seducer - Infused - Absorb Magicka
Necklace - v13 - Footman - Reduce spell cost
Ring 1 - v14 - Footman - Reduce spell cost
Ring 2 - v14 - Footman - Reduce spell cost

All armor/weapons/jewelry/enchants purple.
Mage mundus stone.
v10 trifood.
Attributes: 0 Magicka/(can't remember, but what isn't put into Stam goes here) Health/20 Stam.
Dunmer.
Werewolf.
All DK, s&b, resto, heavy, soul magic, fighters guild, undaunted (only have 1 unlocked atm), and racial passives.

s&b bar: Gdb, Absorb Magic, Choking Talons, Hardened Armor, Pierce Armor, Corrosive Armor ult.
Resto bar: Gdb, Extended Chains, Caltrops, Mutagen/Inner Fire (note: I keep this at its base skill so it stays Magicka), Igneous Shield, Standard of Might ult.


Hope this helps (even just a little). Enjoy.
