Hi Joe
I usually approach at 50kts full flap depending whether I'm two up and fuel load if I'm lightly loaded ie solo with half tanks I bring it back to 45 kts so your speeds converted would workout about right a good thing to do is check your stall speed in all configurations and stay 10 knots above that for safety also increase the margin if it's windy I have a rough bush strip with one direction and on the side of a hill that I fly to on my farm , ranch in your language sometimes if winds are too adverse I don't land and head home rather than risk damage .
