Opinions may abound on this topic, so you might have to pick and choose what you feel comfortable with. Here's my opinion:
Seriously, having "all the tools" and "all the spare parts" would do me no good, without knowing how to fix a problem.
I'd guess learn how to true your wheels in the event you broke a spoke. You shouldn't break ANY spokes though-NONE-you should be riding hand built wheels, built by a knowledgeable builder
who understands your needs (weight+loaded weight+potential riding style). But...sticks, or small animals/children could jump into your wheel anyways, or curious locals could accidently knock your loaded rig over. An accident could occur during shipping as well.
Parts needed to true a wheel include (but may not necessarily be limited to): A freewheel remover tool (like this)
, to effectiveley get to "drive side" spokes. Spare spokes (say 4 of each size-from the person who built your wheels). A descent spoke wrench.
A new rear deraileur & brake cable, these can be trimmed if needed for fronts (borrow a cable cutter from a local-or roll up & tape the unused portion until cutters can be found).
A spare set of "good" brake pads, especially usefull if traveling through country with massive climbs/descents.
Spare cartridge bearings (examples include: pedals, & hubs), provided the parts are "user serviceable". Examples include (but are not limited to) Crank Brothers pedals, Chris King&Phil Wood hubs. Some might suggest a bottom bracket tool&spanner&spare bearings, I'd submit that perhaps this goes too far. None needed if minimal wear prior.
Spare dropouts/deraileur hanger (provided its a steel frame), to be welded while on tour in case of failure (ie: from someone dropping your bikes).
Spare nuts/bolts of all needed lengths (including a spare seatbinder bolt). You should try and have all the bolts on your bike (including racks/fenders) fit the same allen (hex) wrench size, or at most, 2 sizes (ok 3 if you include crankbolts). For allen wrenches, you shouldn't rellie on ones in "multi-tools". These are usually not long enough to provide descent torque when needed-never go "crazy" & brake bolts though. Get one each of "long" ones from a hardwear store (ie Caftsman, or comparable brand tools).
A chain tool, as well as a spare master link, or "Quick link" perhaps a length of 6 links. No need to carry a spare chain, rings or cassette for a 3 month tour-provided drive train wear is minimal prior.
Spare cleats&cleat bolts (if using clipless shoes), again not needed if minimal wear prior*. [*However I do a goodly bit of walking while on tour, and this can accelerate cleat wear-so for a 3 month trip-I'd bring spares. I can usaully get a year out of a set-but better safe.]
I wouldn't bring spare "quick" release skewers. I'd swap them out for really good ones or even better, swap them out for the bolt on type.
A small bottle of chain lube (if synthetic) for your chain+any moving parts (deraileur etc), or a large bottle (if wax) for the chain-as well as a small sythetic for the moving parts.
2 innertubes, patches from 3 kits-with 2 tubes of patch glue. (3) Good tire levers.
Pump (that I'm used to), but not too worn out.
As far as a spare tire-I wouldn't bring one. I would however start with relatively fresh tires that I'm used to (particularly that I can easily mount&dissmount with tire levers).
Various adhesive&tapes. Duct tape, electrical tape, super glue gel, mcnetts seem sealer (for my tent/rainwear-but also handy for panniers), thermarest patches (also can be used for my panniers).
I don't have a need for a spanner, pliers, or cutter-if a need would arrise I'd improvise or borrow one.
This may seem overwhealming, however everything fits into a small ziplock bag!
I also submit that a new bike, or a bike properly maintained (by a knowledgeable professional, aware of the users intent), should have zero mechanical problems for a 2-3 month "rough" tour. Perhaps have it gone over very well at least a month before departure by your trusted mechanic-thus giving you enough time to take it for long (perhaps loaded) rides, making sure everything is nice&adjusted.
The biggest concern I have, is damage in transit to my start (say from baggage)-and even that isn't too large of a worry for me-as I don't even box my bike for flight. I figure, that if something were to happen in transit-there would be some type of shop at my arrival city.
