preferred routing into Rhode Island

I have flown into Rhode Island several times, and always file direct.
However, as I begin to approach the area (about 150 mi out) ATC gives
me ammended routing. My problem is that I am unfamiliar with the
navaids/airways in that part of the country and it adds a lot of
stress to the flight trying to locate the navaids/airways and then to
put it into the G1000. I don't keep my paper scraps so that I can't
look up what ammendments I was given. My next trip there will be in
early March, and I would like to be better prepared. Does anyone know
what the preferred routing is when approaching from the west. I will
probably go into KOQU (I like the FBO there much more than KPVD).
Thanks,
