G'day Chris, The link below is from a thread a couple of weeks ago. It's about a free program that is called Astroplanner. I had never heard of it before reading that thread and on investigation it is a great program. It will do all the things you ask for and more, and its free. Take a look and let us know what you think. Towards the end of that thread I have posted some screen shots etc.
