Lots of good advice in the responses above!
For effects, definitely think about overdrive or distortion. You can set it so that it's not really discernible when the guitar is playing chords, but when the guitar solos, the bass notes will sound really full and harmonically complex.
Also -- listen to live recordings from 80s/90s 3p (and/or 3p + vox) bands to get ideas of what bass players in those bands did (e.g. U2, REM, plenty of others). While you're at it, give a listen also to some of the classic 3p bass players from earlier eras (e.g. Entwistle, Bruce, Butler, JPJ, etc.).
