Your rear der should be ok? The gearing you have looks well within its capacity. I have the same era Deore non-rapid rise on my Appaloosa. Works fine. Sure the chain flops a bit but nothing of concern. I do have a chain stay protector though, actually one of those deore shark fins that also somewhat prevent the chain from getting dragged between the tyre and chain stay (which used to happen).
