I dont mean to sound rude but I really doubt you have read all the threads (or at least a significant amount of them) in that subforum, past page 1 too....
For example a lot of your doubts about how the effects are, can be answered in this thread, which took me 1 minute to find:
plus a bunch of other threads there.
You have to understand where Im coming from when I say what I do. We have this wonderful forum which Im glad you want to be a part of. In this forum there is an incredible amount of knowledge, and we are all very happy to help newcommers with a good attitude to find whatever information they want, to teach and learn, to share and receive. But this forum has been growing a lot lately, and there's a lot of people that register and ask all sorts of questions that a few minutes, or a day, or two, or a week of reading would teach them (and teach a lot more in the meanwhile too). And when people start making all these new threads with all these questions that have been answered a bunch of times, the forum gets boring, repetitive, cluttered up with a lot of threads that end up making the real informative threads hard to find. It makes the quality of the forum go down drastically.
Its nothing against you personally, on the contrary, but if you want to learn, you (and all others) have to make your part in it. Im sure you know that the best things in life we have to work for, they dont get spoonfed to us, and if they do, then we dont appreciate them enough. So please, do your part and research, take a few days or weeks or months or lifetime of reading, there isnt a better forum on the internet for this. Make your part in the learning process, and we'll be more than happy to help you. I know im always learning here and there's infinite more to learn.
good luck.
