Yes, the knobs on the bridge will let you move the individual saddles forward and back for intonation adjustment.
If the hum cancelling procedure doesn't make it quiet enough, then this bass might need the series electronics upgrade procedure to become quiet. That will probably be in the neighborhood of $1500 if it needs doing.
Early basses typically had a core body wood and only a single laminate each for the top and back. It was later that they started adding the intermediate laminates.
Oddly, I'd say that the picture shows the fretboard as lighter than I would expect for ebony. It could be the color rendition of the pic/computer, the ebony could be in need of some oil, or the board could be something else (rosewood?).
