Exchange 2003 on W2K3 - /3GB /USERVA=3030 Setting

Hello, I just wanted to make sure I was reading my KB articles right before I made a change to the server.  I have a Server 2003 box w/ Exchange 2003 and 4GB of RAM.  At the moment I don't have any memory tuning entries in my boot.ini file.  Tell me if this is proper or if there are more settings I want to consider (ESE Buffer Size, Store Database Cache Size, etc...)

I was thinking I just want to throw in: /3GB /USERVA=3030 and leave the registry hacking alone for the time being.  Does this sound good or do I really want to mess with the more advanced tuning.  I have about 60 users and 80 Mailboxes with Exchange 2003 and OWA FE/BE combined setup.  

On a side note, what are the optimal Processor Scheduling and Memory Usage settings to apply in "My Computer->Properties->Advanced->Performance->Advanced".  I currently have Processor set to optimize 'background services' and memory set to optimize for 'programs'.  

I will slice up points for thoughtful info (I have KB815372 and KB810371, no need to post links)
Thanks for the time!

The best thing to do would be to run the Exchange Best Practices analyzer, or exBPA. This will tell you exactly what settings/changes to make.

The BPA doesn't tell you everything. Have a look in the system event log, Exchange will often log an entry in there at startup time to indicate sub-optimal settings, although it mainly points at kb815372 which you've noted above.

I ran a basic report and found the following:
-global incoming message size not set
-global outgoing message size not set
-3GB not set
-'HeapDeCommitFreeBlock Threshold' not set
-Background Cleanup is missing
-Background Cleanup is missing

Thanks for everything so far, I will give it a day to see if anyone else has tips then divy points!
