I doubt either will take any harm, being quite hardy in the area. However, next time do your research on new things. Knowledge is not a bad thing.

I doubt you will have any long-term damage, and there's nothing you can do at this point to minimize any possible damage. Just leave the plants alone and let them be instead of trying too hard to fix things and possibly causing worse damage. The worst that could happen is that the pruning will stimulate new growth which then will freeze and die. If it happens, just wait until the proper time to prune in late winter/early spring and then prune off the damaged wood.

In the future, research first before you prune because different plants have different needs. There are some plants that only bloom and produce on old wood, for example, so if you prune those at the wrong time, then you're pruning off your spring/summer blooms in the fall or winter and your plants will skip blooming that spring/summer. There are other plants that bloom and produce best on new wood, so you want to prune those at the right time to stimulate blooming and fruiting in the right kind of weather. It is so much better to research first and avoid doing damage in the first place, and if that is the main thing you learn from this poorly-timed pruning, then you've gained some valuable knowledge.
