What to learn and what not to learn?

[roshankapoor]

I am a drummer mainly. I want to get into bass and electric guitar because I have the urge to write and compose songs. And I need both of those instruments for that. I do not want to be a shredder or a guy who know everything about guitar. All I'm looking forward to be is a guy who feels comfortable when playing. I want to be able to play what I can imagine in my mind. What topics/techniques should I learn to achive my goal?

I really dont wanna get into reading music and stuff. Tabs seem easy but notes are not I guess. I'd prefer avoiding these
