Definitely do the pads at the same time.
These have a completely logical and simple set up and 99.9% of the time come off with no issues*.
You will need to:
Remove the caliper and tie it p to the spring out of the way
Then remove the caliper securing bracket so the disc can be withdrawn. Usually there is a torx screw locating the disc, try to undo this when the assembly is complete.
Make sure you have the correct spanners /allen key / torx driver or whatever before bashing on.
* the .09% means the disc has stuck to the hub, and has to be sliced away with an angle grinder - nothing to worry about that anyway.
The hub that the disc mates to must be perfectly clean and rust free....have some emery paper standing by!
