As to reading the bass clef. My teacher had me recognize the name of the note and verbalize that name. When I could do that in the same amount of time it took me to say my full name - then and only then was I turned loose on my instrument - which at the time was the keyboard. Try this:

You can practice reading anywhere. Take some sheet music with you. In your briefcase, lunch box, etc. and get in some reading time when ever you you have a few minutes.
Remember if we do not read - every day - rust develops.
Then there is that three octave thing. Our fretboard has a full three octaves of notes, if, we have 22 frets. Which means, depending on the number of frets you have, we have at least 5 C notes - three of which are in other octaves. Which C note are you reading and where is
that C on your fretboard? That's step number two.
www.studybass.com has some very good pdf's on this three octave "thing". Go to

Good luck.
