You really should get a manual because of the type of job this is, but here are the general steps.
Remove the tire and wheel. Locate the two mounting bolts behind the caliper and remove. With the caliper still in place, carefully depress the piston using a pry bar and allow excess brake fluid to exit through the bleeder valve, but close it before air gets in it.
Now remove the caliper and pads, replace pads on caliper. With the caliper off, the rotor will come off. Replace it and reverse the sequence.
Again, I recommend a manual with pictures to identify parts and step by step instructions.
