1. It's really up to you. If you're planning to maximize points on FG, equip the other Avant with blighted seal and heresy to compensate for the loss of the Extra Skill. Anima Avant can act as a replacement for trials if you want to increase the health.

2. Dolk and Krantz on the same team aren't ideal because they clash with the same abilities. Personally, I'd go with Gazia/Krantz or Shera/Krantz as subs. If you're asking  about which to use, I'd use Krantz for Trials, Frontier Gate, Frontier Hunter (if you have to), Raid class 3/4 and GGC. I would use Dolk over Krantz as leader and in situations where bc fill is a must.
