Maybe you should remove some old kernels?

There is no "correct minimum size". It depends on what "future" means to 
you (1 year? 20 years?) and how many kernels you want to keep for each 
version. There may be other factors as well.

Considering that on my machine (10.04, 64 bit) there are 35MB in /boot 
for two kernels, I would suggest to use at least 4 times that amount, 
i.e. 140MB. OTOH, Alan is probably right: Drop the /boot partition 
entirely - then you don't have to resize anything now or in the furure. 
(unless you really need the 100MB).
