Topic: New taper needs help with JB3 setup

[IRiver19]

I plan on recording shows where crowd noise is never an issue (i.e. musicals/classical concerts).  I have the JB3 but don't want to spend much more than 2-300 dollars for the other stuff.  Is the SP-CMC-19 a good microphone choice?  http://www.soundprofessionals.com/cgi-bin/gold/item/SP-CMC-19

Also what preamp or ADC should I use to record line-in, if any.  Since the music never gets rock-concert loud is a battery box necessary? 

I'm looking for a setup that will sound better than this file: http://www.easy-sharing.com/361316/For Good.mp3.html

Thanks for reading through my newbie questions.

with that budget I would go with some core sound mics into a battery box thenline into the jb3
