I feel like I'm pushing my luck advising you since I
usually asking for help, but here goes.
I would simply remove the kernel-images you don't want
using apt-get, aptitude or whatever front end you
choose:
"aptitude remove(purge, I like)
linux-image-2.6.20-15-386-generic" or whatever the
name is.
Once you removed what you want, I think just running
"sudo grub-update" will take care of menu.list located
in /boot/grub/ and you shouldn't have to edit the
file.
If you use lilo(prob not)you may have to edit lilo but
it's been a while since I've used lilo.
Hey, I'm no expert but I've done this before and it
worked so I wouldn't be afraid to try.  If I'm all wet
on this then let the experts chime in. If grub update
leaves some residue of removed kernels, I'd just
remove the residue. As far as what to keep, don't
really have any idea but the oldest kernel-image I
have is a 2.6.20-15. The one I use is
2.6.20-16-lowlatency #2 SMP PREEMPT on a 2000 era Dell
Dimensions desktop. I keep one or two extra kernels
just in case one fails.
HIH.
