CD/DVD-rom cleaner
lens cleaner
What exactly do you mean by these?

If you mean one of those lens cleaning discs, better keep the number of an out of warranty service center in that kit too. Those can work, but they are like washing your glasses in an automatic car wash. You'd be lucky if you still have them on afterwards, and they wouldn't be that clean...

A nice magnetic set of electronic (small) screwdrivers, I'd like to add to your list. And since we're talking ultimate, how about a soldering iron, and a chip pulling tool.
