Select the clips desired (use the Single Track Forward tool for individual tracks). CONTROL , . / to pan all selected audio clips left, center or right.

Open the clip into the Viewer, look at the waveform, enter a new In point. No point in cutting the clip back into the timeline. Or, select the edge of the edit with either the Arrow or Roll tool, then OPTION-Left/Right Arrow to nudge it forward or backward, or +- [number of frames]. This "guesswork" method actually works a lot faster because you don't have to enter another interface. Once you get used to the shortcuts, you can deliberately overshoot the frame number (eg. you only need four frames, but you enter eight), and then correct later.
> how can I make all of the clips have that exact volume per track without selecting each track and doing the option/command L absolute/relative thing eight times.
If even that's not convenient enough, you can use the Audio Mixer tool. I find it a lot less reliable, though, since the clips themselves don't reflect the changes made in the mixer.
