For adding the lines, yes. Take a look at ?panel.functions and ?llines.
I'm not sure what you mean by 'assign values or labels to the lines on the alternative y-axis'. As a general rule, panel regions are 'clipped', i.e., any attempt by the panel function to draw outside the panel has no effect. This can be overridden by with lset(list(clip = list(panel = FALSE))), but I wouldn't recommend using it unless you know what you are doing.
