...and by "Plots" I mean goals that the NPCs have.
I have some questions about this.
1. Is it bad to have too many plots?
2. How many plots should you have going on?
3. Does the scale/scope of those plots make a difference?
4. Should those plots sit in stasis until the PCs come along?
I agree with ExploderWizard and FBA827 on pretty much all their points. I also run a mostly sandbox-style for my campaigns.
One key thing I require from my players in the lead up to my current and past campaign was that they provide me some concrete details for where their PCs come from, along with just generic background details.
I use much of what the players give me to create new areas for exploration in the campaign world. This approach works best in a Points of Light setting, which makes it easier for characters to create whole cloth towns or organizations related to their characters. I then take what I was initially planning, mix it with their information, and then I synthesize it all for a baseline starting point to a POL world and a sandbox campaign.
