Hi, I had something similar at Sheffield University (I'm applying for Science not English so thats a bit different too...!) I was told there would be a group task, a written task and an individual interview. I think they may be reluctant to feed you with too much information beforehand so they can ensure you're thoughts and ideas are your own. I don't think they are trying to catch you out, so if they've only provided you with limited information I'm sure thats all you will need to complete the tasks. You sound like you are pretty prepared anyway so I reckon you'll be fine! We looked at past papers and discussed cpd and research techniques, nothing to frightening, and our written task was based on this.
