I would like to know if and how to prune and thin out branches. Our tree is quite old and seems to have a lot of small branches on each stem.

Prune out what is dead and any weak branches, especially if they are crossing other branches. Once the clean up pruning is done, if you have any fruit left on this tree this year, you need to thin it out.
