Yeah, if you're fighting NE and PGG at the same time then you need to pick up the pace. And abandon the Hell Hole if it's giving you trouble; you can always retake it later on when you're in a more stable position.
Did you wait for PGG to attack you instead of attacking them first? You should take the fight them right off the bat. Well, not right off the bat, but after you've conquered the surround neutral territories. And do you have enough generics for garrison duty? First time I played BBA I was in a sort of Sengoku Rance mindset and shunned generics, but you really want as many them as you can to free up your characters for fighting.
On a related note, I'm finding free internet translated Daiteikoku to be surprisingly understandable!
