In Lovis' chamber, jump over the caved in section left of the entrance, turn around and examine the remains of someone who didn't quite make it through...
You could wait until you are a higher level to look into the scrying stone. Alternately, you can return it to the priest without looking into it (after which the exit door by the lake teleporter shrine will be open), but that doesn't work out very well for the priest.
What type of character are you playing? There are a couple areas near where you get teleported that you could run behind. Even if the ghost and undead follow you, they may split up a bit, and when you turn to fight you might be able to get a couple ranged attacks in before they get to you.
For a melee fighter, a level of Life Leech is handy (or more if you have the skill points to spare). Level 1 of Evade is helpful, and for summoning your creature (if you have it yet) or using the occasional spell, level 1 of Mana Leech is handy (though not a high priority early in the game, when skill points are scarce).
