I need help understanding breeding

Hi! So, I recently got back into the game and am currently level 57. I've been really into breeding, and today, I caught my first Jetragon. I really want to make it fast.

I thought I knew a decent amount about breeding and was getting the hang of it. All I was doing was breeding the same Pals nonstop (with the passives I wanted, of course), thinking that was all there was to it. But after reading more and more posts, I’ve realized there's a lot I don’t understand. I'm sorry for the noob questions!

Right now, I have 3 main questions:

  1. Is the Pal Condenser a good tool to use for breeding? If I do use it, will it be the same as breeding where the passive skills I get are random?
  2. I just read about Yakumo today, and I don’t understand it at all, lol. How does it work, and is it good for breeding?
  3. What should I go for on my Jetragon these are my current passive's.
