Are you installing an upgrade or a full version of 98? No matter really and no need to format unless you REALLY want. Just put the win98 CD in the CDROM drive. On most computers, it will autorun. However, if yours does not, initiate the setup.exe by double clicking on it and win98 will start to load. As for drivers, win95 and win98 drivers are essentially the same so unless a newer one is found by the win98 install program, it will just use the ones currently there. Best of luck.
