Shadid,
The best way to proceed is to gather a bunch of scale plans, so you can see what they include, how they show things, etc. There is a broad variety of ways to do this so one plan is not enough - it will only be misleading.
Then.... decide what YOU would like to have on a plan set, and which plans are best at delivering those features, views, details, etc.
In the final analysis, there is no substitute for plunging in and trying it.
Good luck and don't give up.
