Using JR pass in Kyushu

Hi,

I am planning a trip to Japan in 2 weeks, and thinking about getting a 7 day JR pass. I know there is Kyushu Pass, but I am planning to land in Tokyo first. Here is my questions:

1. Can I use JR Rail Pass for Kyushu design & story train such as Aso Boy/ A train/ Yufuin Mori?
2. Can I usr JR Rail Pass for Sunrise nobinobi?
3. I will use the Pass from Shizuoka through Kyushu, can I make the reservation for all the trains that I wish to take including the design train in Kyushu in Tokyo when I land in Japan?

Thanks,
Nikki
