One suggestion. As soon as you get into the room drink an invis potion. If you are getting beat down by the dwarves you will most likely have trouble with Lady J as well. She is argueably the toughest fight in the game. If you use the potion you should be able to pull it off. You can use the warriors special skill while invisible so long as you do not directly target her. Once she is dead SAVE...then if you want you can kill the dwarves...if that doesnt work. Find better armor and weapons. SOME SWORD WITH FROST...so powerful you can spin and freeze them all...then on top of that lots of strength resis and stamina potions....good luck.
