Wow lots of answers. I'm already feeling the smartness rubbing off on me.
Now to my replies:

  1. The 5v and 3.3 are not connected, the diagram only appears that way
  2. I'm using the 7805 replacement (switching) I ordered some 2200uf. Would one 2200 be enough here?
    Also, I ordered an isolated power component to replace that. I'm thinking I'll still use the capacitor with it as well
  3. OldSteve, I'm using a different zener , I just placed the 1N4001 there for the drawing.
  4. Larry, I overlooked that one. Thanks.
  5. Russel & Mark: I just ordered a pack of TVS. Hopefully that can handle the power side of things along with the caps. But what about analog signals? Will putting a zener on each input pin prevent input spikes?

Raschemmel, I could try that as well.
