Updating kernel, no lilo, but grub

Well, I'm trying to update the kernel on a new server. I have everything done. Grabbed the latest Redhat 7.3 kernel using up2date and now want to get the server running with this kernel. Normally I would just edit /etc/lilo.conf, unfortunatly this server uses grub instead of lilo and I've never used it before, so I'm unsure how far I can go without braking anyting.

The grub.conf file reads as follows at the moment:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda6
# initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.18-19.7.x)
root (hd0,0)
kernel /vmlinuz-2.4.18-19.7.x ro root=/dev/hda6
initrd /initrd-2.4.18-19.7.x.img
title Red Hat Linux (2.4.18-3)
root (hd0,0)
kernel /vmlinuz-2.4.18-3 ro root=/dev/hda6
initrd /initrd-2.4.18-3.img

I did edit the file called /etc/lilo.conf.anaconda and made the new kernel the default and rebooted, but it just booted back up with the old kernel.

A little advice on how to proceed would be appreciated. Can I just remove the old kernel from grub.conf and reboot, or isn't this a good idea?
