I am currently trying to create a Members only page, that members can sign into from my home page, After signing up and paying... How do I do this I am lost.

Maybe you should start by first reviewing this thread, and then spending a few hours pencilling up a good schematic to represent your Website Plan .... something you can follow step-by-step to make everything fall into place.

Once you know what you need to do, it's really quite simple to search these forums to find a solution already discussed that makes it easy for you to make things happen just as you designed them!
