Not to worry Hamfish! Get to where you know those notes on the manuscript first. the keys and all that comes later and much easier. By learning those notes you've covered from the low E string to C over 2 octaves higher. After that you can start sight reading those notes,working up from a very slow tempo. Not as hard as you'd think. But you have to do it everyday. The good news is it only takes no more than 15 minutes a day. When you can read quarter notes at 60 beats per minutes then things will speed up for you.
