Perseus: Latin texts, translations, and tools
This site has a large library of Latin texts (click "Classics" on top of left margin). It also has useful tools for translating Latin. Click "Tools" in the middle bottom of the title box, where it says "The Perseus Digital Library." Under "tools" you will find Latin dictionaries, English to Latin translation aids, and tools that allow you to find where particular Latin words occur, either in all of Latin literature, or narrowed to specific authors or works. There is a lot more to Perseus but these are the main things you will need to use for this class.
