PhysMem: 102M wired, 606M active, 206M inactive, 914M used, 109M free
VM: 6.93G + 84.9M 325173(0) pageins, 120639(0) pageouts
is that an unusually high number of pageouts? and ideas what could cause this?
also how do i determine what is taking up the most PhysMem memory??

Whether or not it is high depends on how long your machine has been up and running. Use uptime command to see this.

Well, this is one thing. Another is how much RAM do you have in the machine in relation to how much RAM-hungry programs do you run.

with your VM being at 6.93G and all of those pageouts, that simply means that, during that timeframe, all of your real ram had been used, and there was bigtime swap file activity occurring.
Some things that cause this are:
A) ram-hog apps, maybe several running at the same time
B) poorly coded apps w/memory leaks
C) Background processes running that you're not aware of

I'd rule out memory leaks, if his uptime is only a day and a half. Apps with memory leaks can chew through your RAM, but it's a rare app indeed that can eat up that much RAM that quickly.
This said, what apps are you running? It's possible you're doing several really RAM-intensive things at once. This is certainly possible, but with that many pageouts I would strongly consider investing in more RAM.

That's only 512MB of pageouts in a day, so it's high, but not something you would likely have noticed--depending on how fast they went. The 7GB VM is not what it looks like. My iBook is showing 4GB VM, but I have 128MB of swap files and 640MB of RAM. I also have 75MB free.
use the vm_stat command line utility to watch virtual memory in action:
vm_stat 60
gives you an update every minute.
