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?)

More like:

1st GIG
2nd GIG
first manga series/first movie
second movie
second manga series

The first movie is loosely based on the first manga series and they basically end on the same note so I think it's truer to treat them as alternate tellings of the same events in the timeline.

The second movie however doesn't follow the second manga.  Personally, I view the second movie and second manga series as alternate universes after the Motoko/cyberhacker event.
