I just posted on your question about cameras in the other thread under 'cameras and equipment' before I saw this post. Can I ask a question - have you ever made a film yet? I only ask because as I mentioned in the other post I think perhaps you are trying to run before you can walk. It's just a feeling. Maybe you are making the whole thing too complicated. The films you linked too in your other post are very 'arty' productions, and if you want to make films like these I feel that the equipment, software and processing are all going to pale into insignificance compared to the techniques and creativity needed to produce them. I also see that I am not the only person to recommend the GH2 as a great, cheap camera to learn with.
Good luck
Jim
