I was wondering, how can you pin point if you blower for your AC is going out, because i can have my AC on Full blast and it wont push much air. What could cause this problem? If it is the blower, how difficult is it to take out and install a new one?

The blower motor isn't too hard to replace. The hardest part being getting it past the strut tower brace. Does the motor sound as if it is working properly? If so, you may want to read the techinfo article on the HVAC evap core cleaning.

Does your airflow seem worse on the passenger side? If it is, then, as Archon suggested, it is likely your evap core is clogged and a good cleaning is in order. This will work wonders on your A/C.

when on low, it starts making a virbration noise, kind of like when you have you cell phone on vibrate and have it on a table, but louder, and you can feel the vibration in steering wheel, and blows out little air and i mean little air
