Another good tip is to start building a list of potential PhD supervisors. As you read, are there people whose work jumps out as being particularly interesting to you? Do they have a good academic reputation in your field? At PhD level, who supervises you is generally more important than the uni or department in which you're based.
Also you have a better chance at PhD funding if you can fit your research interests into the specialism of the department offering the funding.
When you start planning your Masters dissertation, try to ensure that it's going in roughly the same direction as your PhD research interests. That will give you the beginnings of a research track record in your field, which will help.
