Laundromatt:
Pedals are such a personal thing. I play lead at a large church (5 weekend services) and we do a lot of Chris Tomlin, Hillsong, etc. From my experience I would recomend in order of importance:

1.) Boss TU-2 Tuner (I know you already have a tuner. This is bullet proof and fast for stage work).

2.) Fulltone OCD (Superb Overdrive and light distortion)

3.) Fulltone Distortion Pro (or distortion of your liking)

4.) Fulltone Fat Boost

5.) Ernie Ball 6166 Volume Pedal.

6.) Delay pedal--your choice (Boss DD-3?).

You could get by with just the Boss Tuner and Fulltone OCD for a long time and do well. I just like to have a little more diversity.

I'm not pushing Fulltone, it's just that I've tried a lot of pedals and we play a lot of services and they have proven stage worthy and are built with reliability and quality.

You might also consider a good chorus, but frankly I believe they are used way too much. Hope this helps.
