1. Yes, if you are allowing changes to both loads and generators, you will need to use dispatchable loads. 2. Since MATPOWER’s OPF minimizes generation cost (negative for dispatchable loads), you will have to define your cost functions to reflect only the cost of changes from your base dispatch point. While it may not be necessary, you might find it simpler to include the base dispatches of all generators and loads as simple bus injections (PD column of the bus matrix), so that the generator dispatches reflect only incremental dispatches.
