First- Your biggest room cannot be larger than 10000 cubes max area. Try adding solids to fix this problem. Or, make your walls thicker in places.
Second- Not understanding. You can make your doors or walls as big or as small as you choose.
Third- You can make a map in sizes 6 - 9 no problem. Anything higher, and you run into trouble. aka client crashes.
Fourth- Lower all of your ceilings until you have reached the 30 cube limit.
Make sure that you are using solids for your walls and not bringing the floor up. You must use solids.
I hope this helps. Let me know if you still need help. :D
