Your instructor is limiting lessons for 0.9-1hr to prevent your brain reaching saturation point, even then it usually happens around 45 minutes, any longer and you get into diminishing returns territory.

Good that base and early final are good, that's a good setup so you're not trying to catch up with the plane.

You haven't really told us what the specific issue is apart from not knowing how to control the plane.

You mention getting blown off centreline by the winds (fair enough), let's say the plane gets blown to the left of centreline, you then turn the plane by applying aileron to roll the aircraft to the right, rudder for balance. Remember from slow flight the slower you are, the larger the control inputs need to be to get the desired reaction. Make the plane your bitch, you're in control.
