May I also recommend
http://www.willbell.com/HANDBOOK/mess. This book is excellent for learning the key stars to assist in star hopping year round and of course finding the Messier objects. The marathon observing sequence is written for the northern hemisphere but if you're not doing the marathon it doesn't matter as the book is invaluable in learning how to hop from one object to another.
Enjoy!
