    Yes, you can prune out the dead growth. In fact, you can cut the plant back by a third of its growth to help rejuvenate it, though this will affect berry production but if it's looking poorly anyway, this shouldn't be an issue right now.

    If you have had a lot of rain and the drainage in the area is not good, it can cause problems with leaves. Is the ground swampy? If the ground stays wet, the roots can't "breathe" and falling leaves or yellowing would be a sign of this. Too much water causes iron chlorosis.

    The insects are likely visiting for pollination.

    The second one that is not doing well may have a fungus or pests (or both). You can remove the dead branches, but I would treat the plant with a pesticide and a fungicide to treat both possibilities. I personally like neem oil as it is both a pesticide and a fungicide and is organic.

    Yes, new growth is much more cold tender than mature growth as it has not had time to toughen up. If it is brown and the stems are brittle, then you can remove it. If the stems are still pliable, I would leave it as it may still regrow leaves.
