reducing size of apache instances

My Apache 2.2 instances are running about 18 Meg each. I've been 
thinking about doing something to trim these down, and I think tomorrow 
is the day to take action. They are getting out of hand.

I've done a bit of research on this. I think the way to get started is 
to eliminate unused modules. Problem is, I know which ones I need, since 
I purposefully added them. I *don't* know which ones I don't need, if 
you see what I mean, since I inherited them from the default configuration.

I assume that some are critical to the basic operation of Apache. I am 
hoping I can google a list of these tomorrow. Obviously these I'll have 
to live with.

But what about the set that is left after I remove the ones the system 
needs, and the ones I need? How do I know which ones I can safely turn 
off? All I can think of is a trial and error process (i.e., turn them 
off one by one and see if anything breaks.)

Is there a better way?
