The links above provide information on stars near the sun, however, some of the information is redundant. Star Info Page 3 provides right ascension and declination which might help with creating 3D starmaps.

I have been unable to locate my 3D starmap. If and when I find it, I will post it here, along with a table giving the distance between any two stars. Determining distances between stars should be easy enough given distance from the sun, ascension/declination, etc.

For more valuable information and perhaps some 3D starmaps, see Dean's Space Links.
