Correct order of Ghost on the Shell stuff

I've recently acquired all Ghost in the Shell anime that exists. What is the correct order to watch it?

My guess:

First movie
1st gig series
2nd gig series
Second movie (Innocence)

Also, where does the Tachikoma special stuff fit in? Did they show one of those after each episode of 1st gig? (or 2nd?)

I'm guessing because of what happens at the end of the 2nd gig.
