I have a 2002 ES300 and the only issue i'm having right now is this weird squeaking noise that seems to be coming from the outside of my car. But it comes and goes as it pleases and is louder now than before. Any suggestions?

Check your belt tension.

listen to see if gets worse with braking. I suppose if the pads were very thin, then the warning would sound all the time.

give more description like when does the sound heard 1st, @ any particular speed?, happen with braking or with turning etc...or better yet have it video recorded as a youtube ..

I'm not sure of the issue at all, im fairly new with cars but im almost at 100,000 miles and wondering if it could be the timing belt which is going to be replaced this week. For the first time today I had the car in park and I heard a weird knocking sound. Sounded like it was coming from the engine, or something could actually be loose

Timing belt would NOT cause a squeaking noise because it does NOT slip like the other belt. If the timing belt is "slipping", your engine will not run.

Is the knocking noise proportional to the engine speed?

Since you are not very good at describing the issues, maybe have a mechanic take a look at your car.
