vbadvanced dynamics might be a good fit but I haven't used it myself.

I have used vbadvanced links directory. It allowed me to add custom fields for the extra info (address, and all that). I did some template tweaks to show it the way I wanted it. This was a while back ... I had to also edit a few things so a url wasnt needed.

Regardless of what system your using, you can use phpmyadmin to upload a csv file into the database. You can use excel to save as a csv file.

Whatever system you go with, enter one set of data, and then download those tables as a csv file. Open it in excel and just add the rest of the data. Save, upload, and your set.
