Create your own layout. Don't use a pre-printed form off the internet.
There is no need for expensive folders for your application documents as it is common practice in Germany. Some hospitals even consider faxed applications. However, using a clear layout and clean paper will increase your chances.

British CV's do not need a passport picture. So, don't use a photograph unless explicitly required (e.g. in some application forms).
British CV's also have a short paragraph about your "Career Aim". This consists of a few lines explaining why you apply for this particular job. German applicants are used to write this information in their covering letter, however, in many cases this letter will not even be forwarded to the consultants of the interview panel.

Try to make your qualifications comparable to British qualifications. If necessary, explain marks and scores you achieved in exams. Give the British equivalent to the exam you passed.

At the end of your CV there should be a section of "Referees". These are physicians or other respected persons that are willing to give information about you and your previous performance at work. It is not common to enclose written letters of reference "to whom it may concern" with your application. Instead the referees stated on your CV will be contacted by phone, fax or letter once your appointment is considered. Therefore you should only list referees that are able to speak English.

Sometimes, not only a CV is required but an application form that will be sent to you from the medical staffing department. Try to get the document by email or on disk and fill it in with your computer. It may not be enough to fill the sections of this form with "See CV". Unfortunately, these forms are common practice and take a considerable amount of time to fill in.
