For what it's worth I learnt at a field with 1000ft circuit....my approach was aways turn base at 1000ft...pull off power...slow down...1 stage flap and start decent. Aiming to be around 700ft when turning final and adding a second stage of flap (that was in a C150 at a longish runway so rarely used full flap).
At the end of the day, on your first attempt you'll learn pretty quickly whats looking good, and remember a go-around is great practise...its just like a landing but without the fee.
