Which brings me to the chief question, how big of a factor is epigenetics in regards to the evolution of life? If it is a big factor, would it contribute to punk eek in that populations would be able to physically change rapidly in response to environmental pressure without the need of a DNA mutation?
No.
Epigenetic changes done add to each other; they only act once. This means that, unlike mutations, lots of epigenetic changes don't add up into big phenotypic changes. Remember, as well, that epigenetics aren't a seperate thing to genetics; epigenetic changes are possible only where the genes allow.
(Oh, and Punk Eek is mostly wrong, anyway)
