1. My daughter did something such as what you are doing. She found that you need to go to your City Hall's Inspection Department and they will help you. By the way, your plan has to be to their specifications (called Specs for short). I applaud you for taking this on your own.
2. You can draw them up anyway you like, 1/4 inches, cm, whatever, the only thing is, is that your plans have to be approved by local authorities, and even if they are that doesn't mean they are to code. make sure everything is built to code or this will cause your more money.
3. Generally speaking, the lines or squares can be any metric [read: measurement] you want... They can be 1 inch, 1 foot, 2 meters, 10 feet, et cetera. I tend to prefer 1 square = a square foot. But I have done it where 1 square equaled 3 feet. The idea of a plan or diagram is that it be uniform, consistent, and balanced toward whatever is drawn. [to "scale" if you will] Does this help any?
4. what you mean is ..what scale to use ..here in UK norm is 1 in 50 and 1 in 100 ....you can buy a scale rule from w h smiths
5. why not ask your dept which scale settings are required if any sometimes your scale will have enough information then there are no grey areas
