I always tell people for camera selection, which ever one feels most comfortable in your hand to you. I've shot most cams out there and I'm a nikon guy. If you are just looking for stop action then you really don't need a 5 frame cam, especially if you are a beginner. Cameras that are 5 frames or more tend to be more of a pro camera anyway. Once you get use to manipulating the aperature and speeds (also use to the iso speeds for different lighting, pushing and pulling) then I would say, if you want to upgrade, go towards a bigger cam. As for editing, you don't want to do too much cause then the shot starts to look fake. If you've got it you've got it, if you don't then you don't that's all there is to it.
