First, 3 Woodcutters, 1 Forester and 2 Sawmills are a good start, add 2 Wodcutters, 1 Forester and 1-2 Sawmills later. The second additional if you have woodcutters somewhere just to free some space for e.g. farms. One Iron smelter per Armory or Metalworks.
2 Farms per Mill, 1-2 Bakeries, if you have multiple farm-complexes. Don't build Pig farms, the use more space than windmills (2 big, 1 + 1 middle compared to 2 big + 1 big + 1 middle) and you don't get any advantage from it - the guys in the mines eat everything, not like in Settlers 3 where they prefer foods. One Farm for a Donkey breed or Brewery is enough.
Build a lot of Storehouses, you should have at least one anytime on your screen. Keep roads short, putting everything that belongs together (like mines, Iron smelter, armory and metalworks) close togehter, connect those complexes with storehouses.
That should sum up the most important things, there are a lot of german fan sites with more and detailed information, google and it's translator should help to get an idea.
