If I travel by means of shinkansen and limited express trains, will that shorten the travelling time from kusatsu to fukiware falls by half?There are no shinkansen trains between Kusatsu and Fukiware Falls. But there are infrequent limited express trains, which could save you about 20 minutes. So, basically, the express trains will not considerably reduce the travel time.
Will I be able to cover both Fukiware falls and Kusatsu if I set out extremely early from Tokyo like 6 a.m.?Yes, it is possible, but you would be spending a lot of time of your day in buses and trains rather than enjoying thebaths and other attractions of Kusatsu. Fukiware Falls is nice, but personally, I think it is not worth the effort involved in going there. If you have only one day, I recommend to go just to Kusatsu. And, if possible, overnight at an onsen ryokan in Kusatsu (and maybe visit the falls on the second day).
Do you know where I can find the bus schedule (for the month of Decemeber) for the following routes:The exact timetables for December are not published yet.
1) Naganohara station to Kusatsu Onsen (both ways)There are one or more buses per hour, usually well coordinated with the arrival of trains.
Here is the current timetable (I doubt that the winter timetable will be drastically different):

2) Jomokogen station to Oigami Onsen (both ways)
3) Oigami Onsen to Fukiware falls (both ways)
The same bus line connects Jomokogen with Numata, Oigami Onsen and the Fukiware Falls. Note, however, that Jomokogen Station is only served by shinkansen trains. If you go from Naganohara-Kusatsuguchi to Oigami, the shinkansen via Takasaki will be much slower than non-shinkansen trains via Shibukawa to Numata Station. Therefore, you better go to Numata and catch the bus from Numata.
Here is the summer timetable (I doubt that the winter timetable will be drastically different):
