I don't think you can boot from an extended partition directly without a

I don't understand what you mean. I intend to install GRUB on the MBR. Can /boot be a logical partition then? (Or do you mean a bootloader on the boot sector of the logical partition?)
AFAIK grub/lilo cannot find the kernel if it is on a logical or extended partition, they specifically require the kernel to be on a primary regular partition. On the ix86 platform using DOS disklabels you can have up to 4 primary partitions. One of those 4 can be an extended partition which can then have many more partitions created within it. grub/lilo can't go through that many levels of partitioning so they need /boot to be on one of the 4 primary partitions.
As for the size, I think 32M and 100M are reasonable seeing as most
drives are >=10G these days but if you want a smaller one, it's your
box. Even with 5 kernels on /boot you could probably get away with 16M.
I think it's more of a "why not" situation where if it is ever needed
for whatever reason, it will be there.I see. So there is no special reason, except perhaps keeping several kernels? For example, is /boot/grub expected to get fat?
Exactly... You don't necessarily need much space there but with disk being so abundant these days it's safer to give more than you need just in case. I personally wouldn't expect to need a boot partition much over 15 megs ever but who knows what the future may hold... a new boot loader could come around for instance which needs more space.
