IMO a good thing but not great. The postinstall script for kernel-image
.debs limits you to two kernels, which will be called /vmlinuz and
/vmlinuz.old.
If you use grub and run update-grub after each kernel installation/removal,
you can have as many kernels as you wish.

You can fix that by purging the kernel-image packages for the kernels you
don't intend to use.

Change that line to "boot=/dev/hda" and run /sbin/lilo. With this line
you're not telling lilo where /boot is found, you're telling it where to
install the boot loader.
I suspect you answered the question about installing a boot loader in the
partition boot sector "yes". Not the best move.
To use lilo to boot the machine, the boot loader must be installed in the
MBR, which is the first sector of /dev/hda (or /dev/sda if you boot from a
SCSI hard drive).
