You don't need to be fussy about pruning them now. Wind rock can be a serious problem for roses over winter. The instability allows water to collect round the roots and subsequent frost will freeze the water collected killing the rose or seriously weakening it for the next season. The wind this evening will cause serious damage depending on where you are, it's howling here, just an angled cut and firm them in with your heel afterwards. Don't worry about looking for outward facing buds its getting colder and there won't be new growth. Next spring you can worry about the necessary pruning regime. You can mulch them now of you wish as it will rot down over winter and be a good start for next spring.
