So I’ve been putting this off until the lightning season, and now it’s time. How do I protect my transmitter from lightning? Is there some sort of RF surge protector I can get/make? Somebody told me to use a stick of graphite. Would this work?

For a start, whatever pole you're using for your antenna should be grounded properly.
For details see rules for lightning-protection for the buildings.

This rule applies to all antennas in general, TV reception and others, but is often not followed.

Next, if you use a dc-shorted antenna, such as predator or ovc or many other antenna types,
such as our rpl0205, they represent a short to the lightning. Of course you still have lightning on the
outer shell of the coaxial cable so the antenna pole should be grounded.
