The Internet Stellar Database allows to to search for a star and find out its various catalog names, spectral data, coordinates, and distance from Sol. Very handy.
If you're interested in calculating the habitable zone around a star, this page is a quick and (relatively) easy reference. Sol Station has got that calculated for you for many stars and has some decent online star maps.
Maybe you want someone else to put in a lot of the work for you. Winchell Chung makes great real world star maps and you can purchase in print on demand a few varieties here at the aptly named 3-D Star Maps.
