Totally adjustable. EAch cog is adjustable as well as the final ratio/drive

whatever they want them to be different for every track, evn driver to driver and possibly session to session

Do they have enough time to change the ratio's during each session? does this happen alot?

don't know about todays gearboxes, but I assume it's similar to 15 years ago.
Does this happen alot? Probably not much when on traditional cricuits with knowledge already, they can estimate with computers I guess esp with the 19k rpm limit.
They must take apart the gearbox and just exchange the cogs.

Here's a good tech paper on F1 gear analysis from a Swiss company (KISSoft) that makes very good gear software:

I would have thought that this would have been decided before anyone even got to the circuit.

Yeah, I used their demo for a practical work for my Uni, its good, but when I asked the price.... ups
too many Euros for each module

Belatti,
How did you like using KISSoft? I have a license for most of the gear applications where I work. I am using it to design the gears for a very large helicopter transmission. It is very expensive but it is the best gear analysis software we could find.
As a side note, a few weeks ago, I was out visiting vendors for producing the gears in my helicopter gearbox. I'm located in southern California, so one of the local gear houses I went to was Weismann Transmissions (in nearby Costa Mesa, Calif.). Weismann built a lot of F1 transmissions, including some for Brabham and McLaren. Pete Weismann has passed away, but his son Chris is still running the business. I spent half a day talking with Chris and he showed me all of the old F1 hardware they still have in storage at their shop. It was pretty neat! Those Weismann transverse designs were way ahead of their time.
