2. Do you need a special drill bit to drill stainless steel?

You need special bits for stainless steel because those bits are usually made out of durable construction such as high-speed steel, titanium nitride, and cobalt. It will also have to withstand the drilling (the wear) and the extreme heat from drilling whereas regular bits probably won't be able to handle it.
