Correct, with the version that was current at the time of the freeze.

Maybe. We can't tell as we don't run Xandros.

Note that CRAN has backports of R for Debian testing.

You get the current R for Debian testing. You would need to call
install.packages() yourself for packages you need.

We cannot and do not know how testing and Xandros mix.

Call 

	sudo apt-get build-dep r-base

which installs them for you (if you have deb-src entries for apt).

One thing you have not mentioned is to backup your Xandros installation, and
go to regular Debian. If I were you, I'd consider that. Just run Debian
testing on the Eee. See eg

  http://syn.theti.ca/articles/2008/02/16/bits-from-the-debian-eee-pc-team

for the latest from the Debian Eee team.
