Starting a spelljammer game.

        I haven't DM'd in over 10 years, and felt the earge to a few months
ago. After talking with a few friends I started a AD&D core rules game.  My
players are very broad minded and very interested in anything new that comes
their way, often making me blink and have to make a few more notes in the
middle of the game.
       After watching a few newsgroups and mailing lists, I have came to the
conclusion, I would like to move my campaign into the Planscape/Spelljammer
universe.  (I'm hopping not to rile too many people with the concept of
combining the two.)

        So far my players have a group total levels total around 16. And
love making new characters on the fly to test out concepts.  It nice to have
a few of the players wander off after a game and come back with a good Idea
for an NPC.

    So to make this short..  Any suggestions?  Things to avoid?  Or even
some NPC concepts?

    Thanks for listening..
