Your installation of R 1.7.x should have KernSmooth installed! It is a 
recommended package.  The later version available only makes use of the 
new documentation features of R 1.8.x.

Not quite (it will install into a parallel directory) but this is 
covered in the rw-FAQ.

Note that quite a few packages need to be re-installed for 1.8.x (if 
installed under a version before 1.8.0).

Also please note there is no R 1.7 and no R 1.8: try looking more closely.
