Remember to honor the experience you are having in the now, rather than spending energy on things that might happen in the future. If you are spending 8 hours on the bike, you want your biking to be fun.
One u-lock is more than enough. Consider flash drives and/or carrying a tiny netbook and remote-desktop into a machine at home or at a server farm. What kind of work do you do? I found working on the road to be almost impossible - I was only able to accomplish anything if I stopped at a library or took a hotel room.
I am all in favor of spending money to make yourself happy. I was just urging you to consider that while touring, you may find that lower priced gear is a BENEFIT because you spend less time and energy worrying about it being stolen or damaged. Go ahead with the Rohloff & the lighting system - just think carefully about every ounce you carry, because they all add up to many many pounds.
