Geez, you guys travel heavy.
Leatherman tool.
Maybe a short roll of duct tape.
Seriously, a basic home repair toolkit includes the following basic tools:
Flat Screwdriver- small and large
Phillips Screwdriver- small and medium
Adjustable wrench
slip-joint pliers
small hammer
3 meter tape measure
Duct Tape
Teflon tape
Flashlight (any kind that works)
Band-aids
A pencil (stub is fine)
Some sort of (sharp) pocket knife
Optional but proven critical are:
Supply of choice curse words
Phone book containing phone numbers of trusted handy friends, plumbers, HVAC people, carpenters, etc..
For Mac repairs don't forget a few Torx drivers. T7 and T8 being the more popular, I believe.
Cordless screwdrivers or ratcheting multi-blade screwdrivers are nice and things up when you have a lot of screwing to do.
Cordless drills and a small supply of drill bits are helpful for making holes where you need them. A combination square level is helpful for measuring, marking, and leveling things. A small crosscut saw is helpful for basic carpentry stuff. Other tools will be accumulated as you learn new skills.
Your local Lowes or Home depot offers classes on fixing stuff, installing stuff, etc. Your local community college, women's center, etc. may offer some hands on handyperson classes.
If you have a friend who is handy, ask them over when you have a job to be done. Don't let them do the job- ask them to show you how do do it yourself. Make a point of not letting them touch the tools. Most people love to teach.
This forum is filled with folk like me who claim to be handier than we are in real life, and we can be a resource for you.
And finally, keep your sense of humor, take digital photos of what you're taking apart while you're doing it. And remember the basic rules of repair:
Work safely. Always.
Wear proper protection. Eyeglasses, gloves, mask, etc. we like you and don't want you to get hurt.
Take your time. Measure twice, cut once.
Keep your sense of humor. Those of us who think we know everything know it because we've already made every bone-headed mistake in the book. Learn from our pain and scars.
And these 'rules' are strictly tongue in cheek:
If it doesn't fit, force it.
If it breaks, it needed replacing anyway.
If you have parts left over, the thing was probably overdesigned anyway.
It's impossible to trim something longer.
You can't push on a rope.
You can't teach a pig to sing. It's frustrating to you, and annoying to the pig.
