In theory this should be a really good thing to do. I presume you are having a THR for osteoarthritis? Such a programme will make rehabilitation of your artificial joint go easier, and get you back on your feet quicker.
Building up the muscles around the hip and knee as you have listed is a great idea. However the way to go about is not just to give you a list of exs but to use the principle of progressive resistance training (usually using weight machines in a gym is the most efficient) - that is you are working against resistance to the point that the muscle fatigues after 8-12 repetitions so that you are optimising the strengthening effect of the exercise. The resistance also needs to be adjusted over time so that it is increased as you get stronger. With a diseased joint you usually need to start gently at lower intensity.
So in practice I would get a programme from a physio rather working off a list of exercises, as they can assess what you can manage and tailor a programme for you.
