Hi roseradish I am not sure what your question is but if you put a picture of your garden now you will get a lot more suggestions. Also if you name some of your plant you want people can give you advise where best to plant.
most people plant taller plants at the back of the border getting smaller towards the front of the border. scented plant near path way etc.
As people have already told you, most if not all gardeners do a bit of trail and error often changing their mind, I do often.
