[Requiem]

So I bought a used Epiphone Les Paul Studio Standard on ebay for pretty cheap (I figure it will be good to learn on until I get good enough to where a good guitar means something to me, and from reading reviews/watching videos, it seems like a decent guitar), and I need to buy an amp now. To the musicians out there, what would some cheap suggestions be?

I am looking to spend less than $150.. preferably way less, but that's probably the high end of what I'm looking to spend. I want something that will get the most out of my money pretty much. The style of music that I primarily want to learn is blues, but of course I like/listen to rock so I want something with enough settings to mess with that will give me a good versatile sound. Also, not sure if this is something that comes on all amps or not, but I need one with a headphone jack, as I have a pair of nice quality headphones that I will be using if I play at night here.

Also, does anyone have some good resources for learning to play guitar? I understand that I'm going to suck ass for a while, and I will be mostly teaching myself, but I do have several friends who play and said they will show me some things to help learn.
