Yes that is a good site. I found this helpful: http://www.cyberfretbass.com/reading...dard/index.php
My piano instructor had me learn the note names first, i.e. see the fly specks on the paper and be able to verbalize the note name - in the same amount of time it would take me to say my name - then and only then did she turn me loose on the keyboard. You can practice that anywhere, just get some bass clef sheet music and practice naming the notes.
After you can identify the fly speck then start finding them on your fretboard.
This two step method helped me.
Just worry with first position - nut to the 4th fret - after you get that comfortable then you can use position locations up the neck.
Read a lot of sheet music. Keep some sheet music in your lunch box, briefcase, by your easy chair, etc. read every chance you get.
