CRX: Noises, Noises, and MORE NOISES!!!

[IbanezRGKing]

I bought my 88 si a few weeks ago. I have experienced noise after endliess noise ever since I got the damn thing. I want to get rid of all these noises so I can make the car what I really want it to be. But almost every few days I hear another brand new noise and it's really starting to piss me off. So, pick a noise from below and see if you can help. Here's the list as of now (in the order that I began to hear them):1. Hum that sounds like its coming from rear. Only experience this noise when the car is moving. It goes higher in pitch the faster I go. And today I noticed that when I turn left the noise will cease and when I turn right the noise gets ever louder. Doesn't really make the noise at low speeds. IDEAS: I have no clue what this noise is! But it certainly is one of the most annoying ones.2. Metal vibration noise. This noise only occurs at certain RPMs. Always at around or just! befor 4000. Sometimes around 2000. It's a high-pitched clanking sound. IDEAS: I think it some part of the exhaust system that's loose...but as always not sure.3. Clicking when turning at low speeds. I know this one is busted CV boots. I'm gonna replace my drive axels...both outter CV boots are busted. Any tips well appreciated.4. Knocking from the rear when braking. This noise sucks. Only when I brake I hear a knocking from the rear when I brake and the knock slows as the car slows. I can kinda feel this in the brake pedal...just a little bit. Ideas?5. Engine chattering. I mostly notice this in the morning on the way to school. I don't really know how to describe it other than "chattering". I have suspisions of misfiring....I suppose I need to have a look at my timing belt, the timing, spark plugs...ideas?6. BRAND NEW NOISE. This one starting tonite. Clicking noise seems to be coming from the engine bay or console. May be my shitty radio jiggling around...maybe the engine ! imploding in on itself...who the hell knows! This one is the mystery n oise.Also non-noise related...my car has trouble starting sometimes...almost for sure if its really hot outside.Thanks for any input...please help me make this car a joy instead of the pain in the ass it has turned out to be.
