Cool.
In that case, I'd recommend you go with a multi-fx pedal first up, so you can figure out how a particular effect pedal affects your sound, without laying out big cash for a single killer pedal. Once you've played with the various effects, you can pick and choose the effects you want, and go hunting.
You're not going to get the best sound out of a multi-fx pedal, but you will get a good idea of the effect the effect has on your sound, so to speak. Here's the Zoom A3, for example. But hang around, I'm sure you'll get plenty of perspectives from other folks with far more experience than I have.

If it were me, I'd be looking for a loop (tons of fun when you're playing alone, creating your own percussive backing f'r instance), echo or delay, possibly reverb, and at the outside, eq.
