The Work Agreement is really important and the best way of going about this is to download a sample and prayfully edit it to suit your capacity and the needs of the local situation. Once that is done it is time to speak to your incumbent or the Rural Dean in time time of transition. That discussion will include a review of your work, matching the needs of the local situation, training that you might need and where to find it and how you see your ministry progressing over the next three years. 

Support of the local people is not just about the PCC passing a resolution, it is about whether your ministry among them is appropriate and valued although the PCC will have to give the formal nod as well. If you serve more than one PCC, they should really all give their approval.
