Answer 1

1. Try dsp.stackexchange.com

2. At 200 samples per pixel, there are several approaches you can try. Whatever you do, it often works best to draw each vertical line both above and below 0, ie. treat positive and negative sample values seperately. Probably the easiest is to just calculate an RMS. At such a low resolution peak values will probably give you a misleading representation of the waveform.
