I agree that it can be a bit overwhelming and there is so much information that sometimes it is hard to even know what question you need to ask. In all honesty, just say that very thing and post exactly what you are trying to figure out. No one here has ever been anything but nice to me even when I asked what I thought were dumb questions. When your head does start spinning, just post in here about what you are watching/reading about and your thoughts. I have no doubt someone in here can figure out what you are trying to... figure out!
Stick with it and good luck. You are definitely in the right place!
