As a player who just started winning reliably on noble, I think I see a problem here. You have a plan before you see your map, and you seem to be trying to make your situation work inside your plan, instead of making a plan for your situation.
For example, I started a game with the idea of conquering the world with roman praetorians, I found myself on a huge piece of land, with 3 AI's connected by a land bridge one square wide. I changed all my plans when I saw that land bridge, and I instead hunkered down, let them fight it out and teched up, and then came roaring out with cannons and riflemen. The point is, you need to look at the map before you try to decide how to play the game. If your map has a lot of grasslands, cottage it all. If you find stone near your first city, and you have a lot of food resources, then try the SE. You will do a lot better if you take a look at your situation then try to make a plan. Also, try to do things that you have not done before. If you suck at diplomacy, try to make one AI your super-best-friend next game.
Oh, and when you are in the first part of the game, chop those trees around your capital to expand faster, and use slavery to rush buildings, that helps a lot too. (It helps an incredible amount.)
