Re: Red Stars: campaign
I know you're not asking for this per se, but I would definitely consider a relatively simple introductory campaign. Don't go for epic scale, and try not to emulate the previous GM. Do a short campaign that maybe introduces a new antagonist, but have a definite ending. Then, at the end of the adventure, talk to the group about what was liked and disliked about the campaign.
I've been in your position before, and while everything turned out well in the end, my initial mistakes caused some turmoil for a while.
Cheat. I don't make up NPC stats unless I need them. I might note COM and PRE scores initially, just for description purposes, but I don't put actual numbers until I need them.
As for villains, unless I intend to use a villain over and over again I'll take a pregenerated villain and give him a different name, different special effect (maybe), and so on. Minor tweaking of powers/stats to fit my needs, and whatever personality I so desire. Again, though, this is only for throw-aaway encounters. I make recurring NPCs/Villains the same way I make my own PCs.
