A good vacuum cleaner for the latter. We used to cover the sitting area of the couch with a sheet and just wash the sheet. I used to vacuum the big bean bag thing. On beds... wash the bedding.

Getting hair off there are rinsable cat hair removers that work fairly well and the disposable sticky ones that work pretty well. Mostly I just kept the cats out of my clothes storage and got used to having cat hair on me during the day.
