Re: Truss rod adjustment needed?
It's a sort of balancing act. The truss should be set so when you depress the 14th fret and 1st fret, there's a glimmer of light between the 7th fret and string.
The height adjustment bolts should be adjusted according to the technique of your picking style. Stand up, and play the guitar while adjusting the height of the bridge. When you're getting maximum tone at the lowest action preferred, you're there.
NEVER forget that the FINAL step is always intonation. Some people check the open note against the 12th fretted note, to make sure they read dead center on the tuner.
I go further in fine tuning, so that the saddle is adjusted to keep everything from the 10th to the 20th fret dead center on the tuner. Chords ring like a bell across the entire neck when you do this.
