Upscaling is worth it, I've watched low resolution movies on my 1080p screen, PC as source. With no upscaling it looks terrible, with it enabled it almost looks HD. ie with cartoons it'll remove mpeg blocking, and smoothen edge lines. Our Oppo 981 can scale DVD's to 1080p.
As for input/output switching you could buy IR controlled switching box, have learning remote so it'll change input on the box automatically. Basically like a av amp but without amp stages inside.
