Lots of great suggestions already.
I would say this, depending on what you want to play, a versatile OD would be a greta choice, if you want more dirt, it's hard not to find a use for a Fuzz on bass, I'd get that before a straight out distortion like a RAT based pedal (but that could very well be you next choice
).
Then, you might want modulation (chorus, phaser, etc). If you want to experiment with that, a multi would be a good choice (Zoom, or SA Orbital).
Then, maybe you want an octave or filter (find an OC-2, maybe an SA Manta).
So many possibilities ahead of you, enjoy!
P.S.: These pedals will be cool with your current setup, they'll also be cool when you upgrade any parts of your setup. Get some pedals, enjoy!
