One thing, turn undead if you don't want to fight them all. I had Aerie invisible and pressed the skull button to turn undead. Anomen is good for doing the same thing too.

No way around the undead horde as far as I know and I did the area 3 times. There is also a trap on the hand...left hand I think. So add that to the list of known locations for traps. Two eyes, chin, hand, and not sure about the head part. As you approach the area, don't go to the middle. You attract alot more this way. Instead, hit the undead button as you get in and slowly proceed so they don't all come at you at once.

I would have suggested you leveling up some before going there but you aren't too far away from the tomb.

Use turn undead in your favor.
