this depends heavily on whether you are trying to map the nearest 100 stars or the stars in the orion-cygnus arm, as you mentioned both
if you are trying to map the 100 nearest stars:
we only know the distance of the galactic center to the sun with an accuracy of within about 1000 lightyears.
most of the nearest stars have a distance of just 300 light years from the sun, and the farthest is just 1600 lightyears
this makes it impossible to pinpoint any of the nearest stars with respect to the galactic center accurately
if you are trying to map the orion-cygnus arm:
you can find a bunch of clusters of the arm:

then maybe you can convert the coordinate systems to galactic
this may help
http://ned.ipac.caltech.edu/forms/calculator.htmlit is important to note that galactic coordinates are actually not centered on our galaxy
