Please check the answers of your questions below:
1) You can modify the look and feel of the time headers using the "MajorTimeHeaderTemplate"
option (for day views). Modifying the groups headers can be achieved using the "GroupHeaderTemplate" option
(only this option is required in "Timeline" views).
2) You can remove the timeslots by setting the "MajorTick"
option to 1440 minutes (1 day) and "MinorTickCount"
option to 1 (only 1 minor slot will be available).
3) Paginating resources is not supported out of the box and it will require custom solution depending on you and the exact setup that you have. As a starting point you can check the following example in our CodeLibrary which demonstrates how to extend one of the build-in views to add custom functionality.
As a bottom line I would suggest to use the "Timeline" view of the Scheduler as it's most close to what you need to achieve based on the provided screenshots.
