Not sure about how you set up on base, 8 o'clock seems slightly early, but if that is what is being taght fine, and 45 degrees turning final seems a little early. For base you turn left to track 90 degrees to the runway (so allow for wind), I teach setting the aircraft up in a descent with carb heat part flap and adjusting power to commence your turn onto final at 600'.
I teach second flap selection after final turn.
When you get to 8) remember to close the throttle, applying some extra back pressure to prevent the nose dropping as you do so, then - hold off, hold off, hold off....
A good landing normally should NOT be power off then on the ground but power off then holding off as long as you can, I tell people they are trying NOT to land!
The rest seems ok, though there may be variations depending on where you fly.
At the end of the day though use the procedures your instructor teaches.
Oh, and get your downwind call in the right place - ABEAM THE UPWIND END OF THE RUNWAY, this means people know where to look for you, if you can't get it in there then call "late downwind".
