I install each new version of R to a directory ...\R\rcurrent (first renaming the previous rcurrent directory to its "official" name rw....). Having set up the shortcut key one time, on subsequent installations I tick the installer's checkbox "Don't create a Start Menu folder".

I keep a separate directory ...\R\library for nonstandard packages, with environment variable R_LIBS set to the directory name.

My miktex.ini file specifies ...\R\rcurrent\share\texmf as a place to look for input files.

That should take care of your points 3, 4, and 2, respectively. Duncan's suggestion of an R_ENVIRON environment variable (which I didn't know about; thanks, Duncan) should take care of point 1.
