Its in the stinker. We've got to be behind techwise, and our economy is one of the worst. That's because we're isolated.
So yeah, let's go coastal, and take advantage of GL and Colossus.
We need libraries, granaries, lighthouses, and harbors....NOTHING else right now. Grow the cities to get scientist specialists, they'll make up for our lack of commerce for the moment.
Edit: By nothing I mean we just need those buildings. We can always use more workers or settlers.
Make sure that we have an explorer or scout loaded into the caravels when we get them. Once we get caravels, they become the top priority. Get two, and send them in opposite directions.
We then need to beeline to galleons...make sure that we have a longbowmen, settler, and worker combo for 2 galleons, and 1 galleon with 3 offensive units (for barb beatdown on new island is necessary)
