Finally got my license and my first car, an 07' Honda Civic. I love the car but I'm having a few issues and want some suggestions.

Ok, first, the squeaky pedal. Whenever I apply the break pedal, I hear a squeak, which I feel is coming from the pedal itself, because even when I barely tap the pedal sometimes I hear it squeak - it's just irritating - and I don't know what it is, nor how to fix it.

Secondly, as I have an LX, I am guessing I have the duller audio system. I'm fine with that, but my driver side speaker doesn't seem to be working. Sometimes it blurts out music for a second but mostly remains quiet - it's irritating as well - and don't know how to diagnose the issue nor how to fix it.

Third, the vehicle is black and has a few small scratches and dents on it. Nothing major, but I want it cleaned. Any ideas how much this costs?

I also like my privacy and want slightly tinted windows. I live in MA, and from what I've researched the following tint is allowed:

Is this an OK amount? I'm more of a stock liking kinda guy and don't wanna mod the car up too much. How much do tinting usually cost?

What other mods would look cool but not over done?

Thanks guys, appreciate any help, signed car noob. :P
