help(library="package")

will give a listing of the functions (and perhaps other information).

For a list of all the arguments and return values I would suggest the PDF
manual pages for that package. These are all on CRAN or can be built from
the latex help.

You could get the arguments from
 library("somepackage")
 sapply(ls(pos=2),function(nm) args(get(nm)))
but that wouldn't tell you want it meant.
