Chulheekim, It is difficult to tell from your post exactly the kind of help you are looking for. You've got some good stuff and should be able to get some very good 'sounds' from it. Are you still in need of equipment? If so what kind?
Assuming you have, or will have, all of the basic equipment, proper set up is essential to getting good sound.
Inattention to room acoustics and set up will almost always result in poor sound. Unfortunately for those who don't know this, they think the problem is with their equipment and they buy and buy and buy trying solve a problem which can be solved as simply as moving a speaker a few feet or inches or deadening a source of reflections.
