I'll second the Realist pick up suggestion. Kind of odd Ron Carter and Niels Pederson endorsed them, because I'm pretty sure neither of them use(d) it.
For amps, I have to suggest Acoustic Image (I have a Coda R). My favorite amp, ever - unless you can find a Walter Woods.
edit: I would also suggest thinking about using a mic/pick up combo. Raven Labs makes a quality blender (like signal blender, not like smoothie blender - get a blendtec for that). Mics specifically designed for bass can get really expensive. I had the AMT upright mic, it was like $650 but the sound I got blending that with my Realist was great.
