I think putting this more in context of AP, its hard to beat Adobe's Creative Cloud, there are so many good tools in it to help improve your AP. I'm on a MAC and still using FCP7x, I guess if I want to stay with FCP I'll eventually have to switch to FCPX -- not looking forward to it.
One thing I'd point out which sounds much more complicated than it is, but we spend a lot of time tuning and tweaking MR's, Gimbals and camera's to get good aerial video then a lot of people take that video and edit "natively" in their favorite NLE. All of these NLE's step on the image and do some pretty funky math in order to be able to edit H264, Mp4 or motion Jpeg, I'd suggest researching intermediate codecs like ProRes on the Apple or Cineform on the PC and then since your just starting out choose an NLE and workflow that best suits your needs.
For example, I don't care too much for GoPro footage but recently I've been shooting with the Hero3 Black Edition in 2.7K @ 30fps, I use MPEG StreamClip to encode full resolution to ProRes HQ then center cut a 1920x1080 convert the frame rate to 23.976 and then color correct it in DaVinci Resolve. This removes most of the "fisheye" and enables me to match my DSLR footage much better.
Do you need to do this, no, but if you want to charge money for you footage you should. I see so many AP videos with encoding artifacts, the footage isn't interpolated correctly or there's a mis-match in frame rates etc.. You can get away with a lot if all your doing is posting to Youtube but if your charging money for your footage and viewing it on Bluray these problems will be evident.
Doing this adds an encoding step and you need more disk space but renders are generally much faster and quality is much better.
