Yes modes and scales are all movable and once you get the patterns under your hands it will be a lot easier to transpose. Also don't hold yourself back from improvising with the scales even though you may not have them mastered. I believe that you should start using them right away as it will re-enforce the learning process. Plus you'll be developing creativity as well. I have a down loadable lesson that starts from the ground up with video, audio, pdf and backing tracks as well. If you're interested you can check it out here.
