MacBook Pro :: Reduce The Wired Memory?

I have an Mid-2009 13 Inch Macbook pro. I decided to upgrade my memory to 4 gigs using thirdparty memory. However, I have noticed that the amount of Wired memory usage has gone up a quite bit. My Wired memory usuage usually goes as much as 900 mbs and this is outrageous because I don't particularly open any major applications. My Kernel Task right now sits at 397 MBs, which is huge as well.

I find that with one firefox or chrome browser open, I can easily use over 90% of my 4 gig ram and that's when watching you tube becomes very difficult 9freezes a lot.I understand that I never had this problem with Windows, or even when I run bootcamp. 

Here is a print out of my processes: 

Active Memory: 1.91 GB
Free Memory: 1.02 GB
Wired Memory: 853.4 MB
Used Memory: 2.98 GB
