There are a bunch of "*.padding" settings that you can change to
control spacing in lattice plots; e.g., see

str(trellis.par.get("layout.heights"))

But you are probably not using lattice as effectively as you might;
consider this single call as an alternative:

xyplot(total + bal + index ~ date, outer = TRUE, layout = c(1, 3),
scales = list(y = "free"))

You'll need a bit more (a custom panel function) to get different
color/pch in one panel.
