Anyway, since it was only one building finding hotspots was an encouraged idea. Hot spots was where you had 2 or more resources in one location. This way you only had to build one building and you can get two resources without wasting valuable villager seconds.
The best defense for your villagers is towers. Some may moan because towers don't provide enough attack, but what they do however is provide a refuge for your vills so they don't get attacked and they don't have to walk all the way back to the tc getting mowed down on the trip.
So there are no resource gather points in aoe3, but all the experts agree that towers are critical for success. What I am suggesting here is that you find hot spots to build your towers. Maybe wood and gold so that your vills can be safe and secure and you can in turn save resources or use those towers someplace more valuable.
