In case you haven't used this guide yet, this Chapter, like all the others, has an element of nonlinearity to it. All you really have to do are those marked as being required; everything else, while very helpful (and typically required for 100% completion), is optional. Below is simply an order we recommend you do the events.
The numbers in the Completion % column account for the percentage contribution of that area towards 100% completion. After the prologue, you should have a level of 1.6%. By the end of Chapter 1, you should have a 25% completion rate.
