Personally, I'd prefer to see an option that guarantees the starting resources won't be very near each other, because it's annoying when you have Iron Ore and Copper Ore overlapping, etc.
And yes, I too highly recommend the Agent Orange mod. Trees are both a pain in the butt and a great help. A pain in the butt because they get in the way, and a great help because they absorb Pollution and thus the natives will attack later or in smaller numbers, compared to if the Trees had not been there.
