Pick up this book for descriptions of the above and below stretches of the Rogue:
We often put in above Grave Creek, usually from Almeda or Argo. From Hog Creek down to Grave is a popular day trip stretch with lots of splashy class II, but it does parallel the road in. There are a couple of great campsites opposite the road that always look intriguing, and a range of drive in campsites from gravel bars to developed spaces on the road side in that stretch.
I've never floated past Foster, but the river flattens out and you leave the main canyon part a bit above Foster. Jet boat traffic picks up significantly as well. I've thought about floating on further, but then I come to my senses and just spend more time in the canyon instead.
