I hate this too. That is a lot of junk to buy. If you think you will be irritated by buying the "wrong" thing, then you should find a friend who's an expert and just do whatever they tell you. If you're not worried about buying the wrong thing, but just want something that will meet your needs, go to Best Buy, and make someone there pick out all those items for you. They are not experts, but they will do an OK job.
