Never listen to anyone who says not to learn theory. Every so often the guys have to run some guy out who goes on about how "music theory is bad just play what sounds good". Learning Theory is a means of learning just what sounds good and makes everything easier.
my best advice: learn every note on the guitar. master it. then learn your key signatures. improvising will come easily (the most valuable skill a guitarist can have IMO)

It would be like somebody saying, "I don't want to use words to talk, I want to just go by feel, I want to rub my penis all over them. I don't want to talk" - John Frusciante's view on people who don't want to learn music theory
Learn about chord construction. It is so cool to just know what chord/what notes you want to get the right sound instead of fiddling around for hours looking for it.
