Firmware updates for G3

Hi folks. I have brought my first mac. It's an old iMac G3, 333 MHz, 128 ram, 6 gig (tray loading). I've brought a new 80 gig hd, 2 X 256 ram and a version of OS X 10.2 for it. I know how to do the thing up, I'm just woundering what firmware updates i'll need to install on the system before hand. Any links to the relivant pages will be greatly recieved.

Many Thanks
