Constant rainbow wheel and freezing issues

Question

Hello everyone,
I have done a lot of reading online about this issue, and I've called Apple a while back, but the issue has returned.
Firstly, I'm on a MacBook Pro 13" from Mid 2010.  It's got 4GB of memory, and 2.4Ghz Intel Core 2 Duo processor.  I've still got over 200GB avaliable on the hard drive.  I'm also running Mountain Lion 10.8.2.  
Basically these are my main issues:
Constant rainbow wheel occurs, probably once every few minutes or less of normal working
Sometimes happens just randomly
Sometimes occurs when I click a new application, new window, spotlight.. basically any clicks
Lasts from a few seconds to much longer, but generally the computer doesn't fully lock up
iTunes music will pause for periods of time, totally just cuts out.. then resumes after a random amount of time
Videos will pause during playback for random amounts of time - both streaming video and downloaded content
Overall slow response time no matter what I'm doing
I have a memory monitor on, and this all occurs when there is still over at least 1.5GB of memory.  I've tried resetting the PRam (?) multiple times, and it used to seem to make my computer run more smoothly, but it no longer seems to rectify the issues.  I've also went into the Disk Utility and checked permissions and ran the disk repair and everything..
I'm not sure what else to try, so any help would be MUCH appreciated.  I'm in university and this constant freezing is not condusive to my learning haha.  My computer even froze up once while typing this post!
Thanks so much in advance.
