Memory leakage / memory problems

Well, I'm not that knowledgeable about Windows either... Looking at  
the Task Manager and the Performance area, which numbers are the  
critical ones to monitor? Is it the "available" memory, and if so,  
when does that number get so low that it becomes a problem? Do I  
watch CPU usage?... or is the "commit charge" info a critical variable?

Thanks.
Richard
