Hi Rebekah, from the Orange Pippin Trees website:
"The main horticultural problem is that the fruit size can be on the small side, so a good session thinning the fruitlets at the end of May is usually called for."
So I think that's the answer with respect to small apples.
As for the new growth being curled up on apple trees, that is usually a sign of aphids and the solution for next year is to place a grease band around the trunk which will prevent ants climbing the tree and carrying the aphids around to all the new leaves (ants 'farm' aphids in this way and feed off of the honeydew they produce as waste when sucking the sap from the leaves.) I use a thick band of Vaseline and since doing this I have had no aphid damage on my apple trees.
BTW, the variety name will likely be "Crimson Topaz" - originally from Czech Republic - not sure where Joanna comes in (maybe from the apple festival at Joanna Furnace in the US?"
