If you feel you need them, just go to a hardware store to get them
You can just use a lug nut to hold the rotor in place while you work. You should also pull the slider pins out of the caliper carrier, be careful not to rip the dust boot. Clean the sliders and use Sil-glyde or similar hi-temp silicone lubricant on them before re-assembly. They are floating calipers, seized or sticky sliders can cause uneven braking.
