Hello Quade,
You need two controls.
To show the latest 6 items you can use the built in implementation
1. Set SortExpression of NewsView control to Publication_Date DESC
2. Under NewsSettings set
Limit the number of items for the entire list to 6
For the second control that will show items from 6 - 100 you need to create a custom control that gets the content items using GetContent method.
The control should inherit from NewsView and you should override the following method.
All the best,
