if you have went through the materials you listed and felt you understood most of the material, then I think you can go ahead and start practicing. It will let you know where you stand and how to move forward.
I have been studying for approx. 1 month now. I have been watching Pod Cast, reading the PMBOK and Achieve PMP success. Should I try and get through all the material before practicing the simulator as I have also purchased the PM Prep Cast Simulator. I am planning to participate in a local boot camp sponsored by PMI in May.
