You see all kinds of different variations - fuggles early/EKG late, EKG early/Fuggles late, Fuggles/EKG/Fuggles, etc. Which ones do you think smell the best? Use those late. I think your fuggles look good. Depending on the AA% of the hops, you probably want to use those EKG to increase your IBUs (so maybe at 60 or 45). And based on your description of what you want, I'd try to keep the IBUs around 25 or so.
I can't answer the 2nd Q. I've only done AG batches.
