A fairly accurate summary. Remember to reduce power once you have achieved (in this case) circuit height and speed. Of course remember to keep a good look out.
But echoing what has been said above, use your instructor. Instructors will have different views on what happens when - e.g. when to put carb heat on - and sometimes it is condition dependent (e.g. when to put flaps on when in cross wind).
So rather than confuse by listening to what we say on here, which will vary from the highly trained and frequent instructor through to the less experienced, you are best getting it from the person you are going to rely on to ingrain your own good habits and routines .
Having said that, something I had hammered into me on base and final was speed, speed, speed, it is amazing how quickly a 152's speed can degrade when flaps are extended - so remember to point the nose down, quickly if necessary.
Good luck. 8 hours might seem like lot, but realistically you've have a break, and got another 50-60 odd pre test to really hone this.
