So, I got shoehorned into running an SR4 game. I've been working my way through it, but I could use some tools for keeping track of NPCs and such. Spreadsheets, especially.

I mean, sure, I could make my own, but I'm lazy. That, and I've seen some references to a GM Tools spreadsheet that sounds handy.

Some good stuff here.

Rules reference sheets, npc and drone sheets etc...

Edit: Good luck with your game, don't let things bog ya down, do what ya need to and keep the pace going. Do your homework between games and like everything else it gets easier with time.
