I'm wondering the first part of the question myself. As for the rest:
The badge cloak is AMAZING. It's a beautiful piece. Personally i'd get that first but ick's is a horrible trinket. I'd go with the Glyph + Black Heart trinkets and get the cape, then farm for the Key.
As for gemming, the way to defeat the 20% dodge debuff is to get more dodge, not change to inferior gemming. But seek that dodge/parry on gear not gemslots. You should have minimal to no dod/stam gems anyway - you only need 1 to activate your meta and the rest is 99% better off with a full stam gem in place.
