Yes, the documentation isn't great at the moment, but I am working on
it. One reason why these two things (adding title and removing
legend) is that I'm still not sure that this is the right interface.

You need to do
p <- ggplot(...) + ...
p$title <- "My title"
I'm planning on adding some methods to make this a bit easier (at
least less typing!) when using ggplot instead of qplot.
