@Nagisa-
1) No, no minimum, just adjust the /players setting until you're comfortable. A +zero skills blizzsorc can do this.
2) Static field helps here. Spam Glacial Spike at the mummies w/ blizz going on them until they expire, then teleport right on top of the skeletons one at a time so your merc doesn't have to wander around decrepified, and while you're there hit Static a few times. If your Insight is in a good polearm, that'll work, but I prefer Reapers
3) I would go with option 2 for your merc. I love Reapers on him. My merc uses Reapers, Ethereal Guardian Angel and Kiras Guardian (for the +res and CBF). He rarely dies, usually to lister&co. or IM clearing the throne.
For all waves, I've found that spamming GS to freeze everyone in place is essential. If they can't move, you and your merc can live. Blizz+GS+GS+GS Repeat. If you're feeling brave then start with GS+SF+GS+SF+GS then go to Blizz. It's dangerous if you get a fast moving pack and they surround you while you're doing this, though.
