You probably don't need to worry about duplicate content. Some SEO's claim that here isn't even a real penalty for duplicate content. The real issue is more simple, how to rank for things using content that lot's of other people are using. This is a problem especially for people using data feeds (affiliates for example) which could be used by a ton of other people. Have you done your keyword reasearch? Are you trying to target certain keywords? Or are you just going for general search engine traffic? If you have done your keyword research then you should probably be able to answer your own question. After looking at the search volume available and competition for your keywords, then you pretty much have a blueprint as to what you need to do. For example, if you are trying to rank for the general term of Blahblahwhateverwhocares, California then you are going to have an easier time doing so than ranking for the general term of San Francisco, California. So, there are a lot more factors you have to deal with before you get to duplicate content.
