Drivers and Firmwear

[VaShaun Jones]

I have not gotten Leopard yet, but I have been listening to the list- 
posting regarding installation. Based on what I heard I still haven't  
decided. My question is did anyone update their drivers and system  
firmwear prior to installing Leopard. Is this essential or even  
needed when talking about a Mac? I also want to know about how to do  
this myself? How do I locate my drivers to compare them to their  
respected download and where do I go to find drivers and firmwear in  
one place for my specific machine? Thanks
