The POH states 60-70kts (no flaps) and 55-65kts flaps down. With short field 54kts with 30 degrees flap selected.
Low hour duffer here also, but remember the POH is for gross weight which probably does not make much odds in a 152 with 2 folks in it, but flying it alone with 1/4 tanks probably leaves you 250-300lbs under gross which if I was flying I would knock 1mph off the approach speeds for every 80lbs I am undermax weight, not sure if this is the correct procedure but it does seem to get me in slower and pulled up quicker.
