Is there any way to keep the spamming lowlifes from using email addresses found on my website? I run a PHP/MySql driven website that allows members the option to have their emails visible. Is there anything I can do to keep them from showing in searches?

A few of my members have gotten spam like this one that I got:
EMAIL (http://www.hostingviews.com/spam.gif)

I forwarded it to SpamCop, but I don't know much about them.

You should be able to disallow whatever robot is spidering you with a robots.txt file. Also you can str_replace() the @ in your email addresses with [at], which is also effective.
