Chris-
For tools we're going with a Topeak Alien XS Multi-Tool-as good as Park and not as expensive.

http://www.rei.com/online/store/ProductDisplay?productId=4957&storeId=8000&catalogId=40000008000&langId=-1 We are going to be riding on Schwable Marathon XR's-26x1.9. We've heard nothing but good things about them from everyone from Robin Thorn to Mark & Ju McLean... they have some added tread and therefore a bit more added grip.
Yes, take 1 spare 16 incher for the miniature human beings trailer. Also a tire/puncture/patch kit- A folding tire, 3 spare inner tubes and some good epoxy glue for anything including tire emergencies and a tire lever or 11. [^]
Essential luxuries e.g. anything that doesn't weigh much! We're planning on these-
1. 1 paperback(not hardback)book for my Mrs. and 1 for me. Good thing here is they don't weigh a lot(unless you're taking Webster's or War and Peace)and when you finish it you hand it to your other half AND then after they're done... stop at a used book store, sell it and buy a new or used one and off you go. We could just use the computer-see below-for reading books online/hard drive BUT nothing replaces the pleasure of "holding" a book in ones hand and sitting back under a tree and reading until you doze off! Sometimes the old ways are best!
2. Digital camera. I really feel like these are better for a number of reasons BUT especially if you're going to be maintaining a website whilst out touring-which we will. Otherwise, camera/film/batteries.
3. Laptop computer. Website maintaince, emails, ordering gear if something wears out, music at night in the tent, watching movies, etc. Or, if you're touring in more civilized areas... Internet Cafe's for maintaining your site/ordering gear/keeping in touch with family and friends and ditch the computer.
4. Power sources for above items... battery chargers and solar panel.
5. Cell phone... they exist so therefore having one makes sense to us-just in case.
6. Essential toys for miniature human beings. We tremble with fear at the thought of 1 or more days locked up in our tent with our 4 year old daughter while it snows/rains/storms outside and she grows bored. [:0][}:)]
7. School books. This applies to us because we will be home-schooling our daughter on the road.
I am sure the list will grow in time... but that's all of our essentials that we've come up with as of now.
Lastly, I'll assume Bek is your wife and say, where are your priorities?? The Mrs. gets the custom bike while yours is Off The Peg??!![:I][
