What goes in a tote or carry-around toolbox?

[redtail]

It seems that all of the tools in my roll-around cabinet tend to migrate to the tote tray of my road trip toolbox. Between the weight problem nearly ripping the arms from the sockets after a while and the frustration at having to nearly dump out the tray to to find the tool I need at a perticular moment, I decided to pose the question to the gang here:

Part A: What kind of carry around toolbox, toolbag or tote tray do you use or recommend?

Part 2: What essential tools do you require?

Part III: Are you organized or do you just throw it in there and dig for what you need later?

Hopefully we can cover the spectrum from the recommendation of having a pen, a spoon and the phone number for the hangar, to having the first hundred pages of the current Snap-On catalog.
