I'm not entirely sure if this would be useful, but I've noticed that I do use wikipedia quite a bit.
That's one thing I'd take with me into the hellish offline world. Probably a really low priority though. But hey, trying to think outside the box here.
The wikidump can be as big as 5GB and as small as 25MB, depending on content massaging and language. Some rudimentary googling turns up
wikitaxi (Windows only) and
okawix (Win&Mac). Setup appears to be really easy.
You already know where you'll be stationed, I guess. Maybe you can acquire translation software for the dominantly spoken languages. If applicable I'd install the IME too. Just in case you might need it. Always helps to be prepared.
Maybe think about installing some sort of VM like Virtualbox, VirtualPC, VMWare player or whatever. Make the images read-only so you'll always have a clean system. Shit happens if others have access to your stuff. It's OK, they'll only install that one piece of software they know, or change that one setting that'll make the thing run faster! Boom.
Have a working backup ready for the same reason. Who knows what will happen. You certainly won't have access to the web for drivers, howtos and updates, so make sure it's recent and correctly configured. Personally, I'd also encrypt the shit out of my personal info and data.
Other than that, I'd go with ebooks (time for a re-visit of ye olden baen library, for example), porn, music, and ROMs. Lots and lots of ROMs.
