Here's my basic repair/parts kit:
small sharp knife
couple of rags
2 tire levers
exta master link and a few spare regular chainlinks
Allen keys: 2, 2.5, 3, 4, 5, 6 mm
miniature screw driver consisting of #2 phillips, #1 phillips, and flathead tips.
brass wire brush
presta to shrader adapter (so I can air up at a gas station in case my pump fails)
2 spare spokes with nipples for each spoke size
small pair of channel locks with the handles cut to about half length (good for taking apart a chain at the master link or straightening a dinged rim)
a half sheet of 200 grit wet-dry paper (to smooth out channel lock marks on a rim, scuff a tube for patching, sharpen a knife, etc.)
a small piece of an old tire a couple of inches long (for a blown-out sidewall emergency repair)
small assortment of 5 mm and 6 mm nuts and bolts
Also, depending on the length and relative remoteness of a tour, I would consider carrying a spare folding tire and a set of brake pads. (Touring through the Great Plains is remote in the sense that bike shops can be few and far between.)
Make sure your bike is in perfect condition when you start the tour, and you shouldn't have any problems with BB, hubs, headset, etc.
Doing a long tour in a remote third world country or backcountry/wilderness setting is an entirely different situation. For that I would consider bringing a full tool kit to service anything on the bike.
