I have two characters who have done this quest; my Nord 2H warrior, and my Archer/Conjurer. My melee warrior was by far the hardest to win this battle with. I had to go through the battle 4-5 times before I finally got him, and I even had Lydia with me. Those frost and lightning attacks got me everytime, and I couldn't get close enough to him before I bit the granite.
My archer was a one-try solo effort. I took out the shades first from the stairs, then poisoned my arrows with Dmg magicka so he couldn't cast, and shortly after he was dead. Took about 7-8 arrows, but I shot from my safe spot in the hallway. Way too easy like that.
That's been my general experience so far. My warrior dies A LOT, because he only wears Steel Plate (cause it's so awesome) and wields his Skyforge Greatsword (cause it's awesome) but that gear doesn't stand up to the lvl 36 resistance I'm meeting, so even though he has 270 HP, bosses take me out constantly.
My archers has 150 HP and wears Saviors Hide, but rarely even takes a hit. I just summon an Atronach to take the punishment, and then finish off the resistance from afar. Cakewalk compared to being a 2H fighter.

Sounds to me like you could benefit from some Frost / Flame Cloak Scrolls!?!?
