Let me offer you a look ahead. At some point your present concerns will be way behind you, and you'll discover that you can use the different attacks to achieve different sounds at will, including using only an index finger, only a middle finger, both alternating, thumb (including slap), muting with both hands and all of it together when the riff calls for it. ...and, you won't even have to think about it! ...your two hands learn what to do so you can concentrate on other things, like singing maybe. You'll just need to check in on your hands once every so often. I know it all sounds very challenging when you're getting started, but it will come if you just do it enough - like practice and practice and get on stage and take chances. Oh, and I suppose you COULD use a pick too
