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?)

For what it's worth, the last scene in the last episode of 2nd gig is pretty much the same as the beginning of the first manga series, which is what the first movie is based on.  (The sakura viewing scene.)
