This can take nine months or longer sometimes. If it is well passed that, and still not ripening, then I would suspect that there is, either, too much nitrogen in the soil, or not enough phosphorus and potassium.

If this is not the case, then I would chalk it up to a pH imbalance in the soil. You can mitigate this by adding dolomitic lime, and iron sulfate to the soil along with your regular fertilizer in the spring.

No, only broken or damaged branches should be pruned.

Those are galls! They are caused by fungal and bacterial infections, specifically spread by insects. They won't cause serious issue to the tree, but you may want to remove as many as possible in order to allow the trees to be as productive as they can. You will also want to treat with insecticides to prevent the issue.
