So I just started learning about economy picking. Is there any good songs or exercises I can practice with?
Gear for the moment:
Epiphone Goth Explorer (w/stock pickups)
Peavey Vypyr 15 watt Amp
Boss PW-10 V-Wah Pedal

For exercises, I recommend clicking that little "lessons" link at the top of the page. I'll do you one solid, even, and do the work for you.

http://www.ultimate-guitar.com/lessons/guitar_techniques/

The front page has several economy picking lessons. It's an extremely common and extremely basic guitar technique. It's not like underwater basket-weaving or rocket science -- the info is all at your fingertips.

As for songs? That's not my department, unfortunately.

Take it easy.
