This one's easy. For example,
x <- rnorm(100)
y <- equal.count(rnorm(100))
z <- equal.count(rnorm(100))
ylabels <- substring(as.character(levels(y)), 2)
## or, if these are too long
## ylabels <- substring(as.character(lapply(levels(y), round, 3)), 2)
bwplot(y ~ x | z, scales = list(y = list(labels = ylabels)))

This might be a problem if you don't want to use the strip function, since a
panel function is usually not sent any information about which levels of the
conditioning variable it corresponds to. With strip, it should be easy:
zlabels <- substring(as.character(levels(z)), 2)
bwplot(y ~ x | z, strip = function(which.given, ...)
grid.text(zlabels[which.given]))

Currently, there's not much else. (Incidentally, everything I used is
documented in the help pages, although they might be a bit difficult to find.)
A web page is in the making (at packages.r-project.org/lattice), but I
haven't
gotten around to really starting it up yet.
