Holy moly, that's a ton of work. I can't help with most of that, but I do know that if you look under the rocker panels of your car you should be able to see the jack pads. They're rectangular pieces of black hard rubber or plastic, about 1 1/2" by 3", and there should be 4 of them.
When I did my coolant flush, I used the biggest disposable aluminum roasting pan I could buy at my local grocery store, and it worked great.
I think the torque wrench I have was from Harbor Freight, and it's perfectly suitable for the occasional job. And, it's a ratchet, which makes torquing bolts in tight areas easier.
