I'm generally pretty happy with how you have the values right now. It makes sense for a looted hold. If there were more players in an area that would be richer (in the lore) it would make sense to have more gold.

Indeed. Ekrund has been in goblin hands for generations (by dwarven standards!). That means that it should be thoroughly looted and desecrated by now. Sure, there will be riches there, but it takes time to find them. And with a war going on, time is a luxury few people will have. The resources seem pretty good right now. Though I would like to see supply lines (maybe in a future campaign).

'cause right now, you have a line going from starting port to armies in the hold. Which should mean easy access to reinforcements, materials, etc. But an army which has supply lines, and one which is completely surrounded (seem to be) on equal footing.
