First off, I hope this one works out better, but to be honest, what you have described (car parked, guys overseas, mother handling it, etc, etc) sounds like a scam, so use caution.
1. That said, what you need to know is what did he do before he stored the car. If he filled the fuel tank (AND added fuel stabilizer) and changed the oil then I don't think you have much to worry about. BUT, I would change the oil again before starting the car and I would put a can of dry gas and a can of octane booster into the gas tank.
Why? Oil goes bad over time. This oil has been sitting too long (no choice - you don't leave an engine dry) and has started to break down from time and turn "sludgy". So change it out to ensure the car gets oil right away. Were it me, I would use as thin a startup oil as I could get my hands on: 0W-30 Castrol or 0W-40 Mobil1, for example. The key here is to get oil to the top of the engine as soon as physically possible. If you can, you'd ideally like to warm the fresh oil up to 100F or so before putting it in the car - put it on an electric blanket, for example.
The gas will also have started to suffer deterioration from time if fuel stabilizer wasn't used. The ideal solution is to drain the tank and fill with fresh fuel. Typically this is a bit inconvenient at best
So put in octane boost to counter the chemical breakdown and add dry gas to help drive out as much water as possible.
Yes, this is a lot of work, but remember - this could be YOUR car next. And the worst that happens is you changed the guys oil for him - big deal!
2. NO - the break in procedure for a new engine is because it has not been run before, not because it is oil starved or has been sitting.
3. You've already changed the oil, but I would do a HOT oil change again at about 500 miles or so later (if you drive it home, do it at the end of the trip) to get out more of the old oil. Change the filter at this point as well.
Plugs don't go bad, so only change them if you feel hesitation or get mis-firing.
Fuel filter probably should be changed as should brake fluid and anti-freeze.
4. During your test drive, remember that this car is running on old fluids, etc. It will have likely have mis-fires, hesitation, all caused by old fuel. There is little you can do except run the tank out and fill it again...
