There is a bewildering amount of advice and video material out there on the internet Peter, the trouble being, that as a beginner you have no way of knowing if it's good advice or bad, and believe me there is plenty of bad advice out there.
As you are completely new not only to pen making but to turning in general, may I recommend two particularly good books to you.
The first is concerning turning in general, and deals with all the questions of tools, tooll presentation, technique etc. It's a pretty old publication now, and in fact its author sadly died two or three years ago, but none the less it is difficult to beat.
Woodturning: a foundation course. By Keith Rowley. GMC publications. ISBN 1-86108-114-6
The second is dedicated to pen turning itself. It's author coincidentally happens to be a member of this forum, and is possibly the best and most comprehensive guide to our craft available.
The Complete Guide to Turning Pens and Pencils. By Walter Hall. Taunton Press. ISBN 978-60085-365-4
You will have to adapt most, if not all of the projects suggested in the first book, as your lathe won't have the capacity to handle them, but the point is, that by following the book you will gain an excellent grounding on how to go about turning on a lathe. The second book is of course all to do with pens, and is also an excellent reference and source of inspiration that you can dip in to time and time again.
