1. I've never died in GWD before 2. I'm known for my ability to bless graves *cough* southrend *cough* 3. You'd still get hit just as much as I would, by the minions XD
As far as I know you don't need any special quests, however if you don't have a Bandos item (like a Bandos godsword) then you should have the ancient mace from Another Slice of H.A.M.
You only need a Zamorak and a Bandos item for kill count.. There are no Saradomin or Armadyl monsters near the Bandos ones. I generally take a Zamorak stole for KC and replace with the fury inside.
