My typical trip pack:
1. Before leaving, good chain and sprockets. (Personal favorites: Honda sprockets, Diamond chain for the long, hot runs). Can of chain lube.
2. Spare spark plug set.
3. Spare points (or points plate, with condensors), and 2 clip leads (from Radio Shack) to use as temporary wiring jumpers in a pinch, or for setting those points, if necessary, using the NEUT light's bulb. If your points and condensors are fresh, you likely won't have any problems, though.
4. Tubes: on 18", the other 19". I carry 3.50x18" and 3.00x19" all the time. Some sort of air supply, like bicycle pump at least, electric pump at best.
5. Check battery for "good" before leaving, and take extra fuses (2 at least). Check the battery every 3000 miles to make sure the water is OK. If you run with headlight on, it will help keep the battery from overcharging on long road trips, and it's safer.
6. Bare minimum: Honda's whole 750 toolkit. This includes 10mm, 12mm, 14mm, 17mm, 19mm wrenches, axle wrench, screwdrivers (flat and crosspoint) with the "T" handle for the stuck ones, and .003" feeler gauge. Add: tiny chain breaker, extra master link to fit your chain, consider a 6" Crescent wrench, too. They will all fit in the toolbag, as will those extra fuses.
7. Half roll of toilet paper. 1000 uses, from wiping hands to starting campfires, and helping out when you find bad food...
Don't forget to change the oil along the way, and use 20w50 for the trip, nothing lighter (except possibly 15w50 synthetics). Change filter every 3rd time on a constant road trip like this one, every 2nd time in town riding.
Take leathers. NOTHING works as well: there's good reasons for bikers and leathers. They don't 'flap' when riding like other materials: this wears you out slowly, so you don't notice it, until you find your reflexes down. Stop and take a drink with your bike.
And think about me once in a while, I'll be wishing I was alongside!
