Hello Lynne

The webbing could be from a couple different insects. It looks like some sort of webworm caterpillar nest. You need to pull the web apart and try to spot which caterpillar is inside. Fine webbing can also be made by spider mites, which need a magnifying lens to see clearly.

Despite its name, fall webworm is active right now. Control for spider mites is different than control for webworms, so it is important you see which is present on your shrub. From what I can see it appears to be a caterpillar( bud and leaves appear to be eaten).

The brown ‘windowing’ on leaves is from feeding by the larvae of rose slug sawflies. The larvae are often on the backs of the leaves.

Here are management options for rose slug sawflies:

Here are some more photos of the pests. The mites will need magnification to be seen clearly.

The damage on the canes may be winter injury or canker. You may prune back to a healthy bud although, if the stem holds many flower buds, you might wait until they open, prune then and keep the flowers in vases to enjoy.
