Yes, jack stands are necessary. The car is not secured on a hydraulic jack. If you're under it and the jack gives out, have fun.
You can buy a 2.5T and 2x jack stands at Cdn Tire for $50. You can take the lug nuts off by hand using the wrench that comes with the car. You really don't need pneumatic tools to do it. It's 16 or 20 nuts depending.
You should use a torque wrench to tighten the lugs back on. Should be in ft-lb, which is a measurement of torque. Read your user manual to see how tight the lugs should be. I would guess it should be in the 100ft-lb range.
