Ok thats much more detailed than the website I read and I understood the concept much better, so since its not very useful should I cut the whole branch off or just the top bit with the leaves
I think you can shorten it. Do not cut any of the lower branches, let them grow freely.
If it is a little princess, it is basally dominant - which means the lower branches tend to grow bigger and faster, which may prevent the tree from developing a good apex - but that is something you won't have to worry about in a long time.
As for the branches I pruned back that was fruit of my impatience although I only cut a few very small ones and pruned them back one or two nodes I hope thats not to bad .
Don't worry about it. You did not remove that much.
