What protective gear should I wear when cutting rebar?

you can use a portable bandsaw to cut rebar, I find it to be the best solution when I can't take the rebar somewhere to cut it. But be careful if the metal is heavy it could fall and dent/damage the floor if you're working indoors of cause injury should it land on you.

You should wear gloves to protect your hands from slips and goggles or face mask to protect your eyes and face from any metal pieces that may come off the bolt you are cutting.

you can, but its not great for the teeth of the saw and it can get tiring. if you have any powersaws with metal cutting blades, that works best. if not, you can use the hacksaw but i hope you don't have too much rebar to cut

i use a sawzall, but you can use almost any saw as long as you put on a metal cutting or diamond blade

The motor is shorted plain and simple. I would just replace it. Buy a Dewalt, they are a better made drill/driver.

Rebar in the ground may be okay for lightning protection but a big no no for electrical work. Rust on the rebar and lack of moisture in the ground (along with other factors) could make for a high resistance, useless, dangerous ground. A good ground has almost zero resistance. If parts of your body have a lower electrical resistance than your rebar setup, YOU will be the conductor! ZZZZZTTT!!!
