Is there any class that generalizes distributions?
For example, I could say
x - generic_distribution(normal, list(mean=1, sigma=0.5))
and then use it like
rgeneric_distribution(100, x) to get a sample of 100, or
pgeneric_distribution(0.5, x) to get the pdf at (x = 0.5).

I think the distr package does this. There are also packages that link

How exactly should I go about turning off annotation when running
Stangle (Rtangle) with R CMD Stangle myfile.Rnw?
Ideally I would like to be able to turn annotation off and on for
individual code chunks, or maybe better, to annotate only named
chunks. Are either of these things easily done?

Try:
plot(0,0,n,xlim=c(0,1),ylim=c(0,1),axes=F,ann=F,xaxs='i',yaxs='i')
To see if that fixes it for you (without the xaxs and yaxs arguments it
adds 4% of the range to each side so that any points plotted do not fall
to close to the axes.
Hope this helps,

You need to set the environment on your version of print.trellis to
match that of the original (at least that is what has worked for me when
trying to do modified functions from the trellis package). Try
something like:
environment(print.trellis) - environment(lattice::print.trellis)
