Something like

xyplot(...

       xlab = list("foo", font = 3),

       ...)

fontface and fontfamily may be specified in the list too, although the
documentation fails to mention this.

(2) how to plot the panels for each level of the conditional

Not possible directly, you have to change the order somehow. The
easiest is to specify the order when creating the factor explicitly,
e.g.

newf <- factor(f, levels = unique(f))

This should work fine even if f is already a factor.
