Glad you found the part you needed. Looks a whole lot better than duct tape. The brush rolls for those older Eurekas are somewhat problematic. I've never had to mess with one as all three of my Eureka/Sanitaire uprights use the hexagonal brush roll ends. That said, if the bristles are on strips, there's no reason why couldn't put new ones in. To my mind, the big consideration would be the condition of the bearings. I replaced the strips in the VibraGroomer brush roll that came in my late '70s vintage Sanitaire SC686 but I found the bearings were shot and I'd done all that work for nothing. I ended up replacing the brush roll with a brand new VibraGroomer II and it now works like a champ. As far as the bag goes, the color looks fine and if it works okay, I wouldn't worry too much about it, at least until you've got the brush roll sorted.
