I wonder why most of this software only allows the image to be saved as a
.bmp without a choice of saving as a .jpg.

I have to admit that I'm not too up on these things technically, but the
resulting image I get from an image compressed down to even 50k on my
ancient 1.3mp Olympus digital camera is infinitely better than what I'm
capturing as a 300k .bmp using a cheap webcam or security camera... all
very
disappointing.

It's all down to the software and quality of sensor in the webcam.
Most webcam security software will allow the native .bmp to be
compressed to the lossy jpeg format for transmission by email,
ftp'ing to a 'live' window on a website etc.

The Sony CCDs are the best for low-light, but most webcams only
have CMOS sensors. Unfortunately the OP's QC5000 can come with
either CMOS or CCD sensors, but probably CMOS in the UK.
The resolution of the sensor is the other thing - most are 640x480
pixels, so images will never look as good as from a digital camera.

The current webcam of choice for low-light is the Philips SPC-900,
which uses the excellent Sony ICX098BQ CCD sensor.

HTH,
