How can I check to see if my spark plugs are actually sparkin'?

The quick & dirty way (well not so dirty) that I have used is to just hook up an inductive timing light to each sparkplug lead one at a time & then crank it. If you get a flash then it's firing.
This will NOT tell you what condition the plug is in, etc., but you will know very quickly if it's sparking or not.
