Starting Strength has a lot of good resources on how to do the basic lifts, progression for novices, etc.

The Starting Strength book is really good if you like to get into the science-y stuff on why it works and why barbell is better than machines and cardio.

You definitely want to learn the proper forms from a friend or a personal trainer, though. Proper form will make all the difference when you start advancing to higher weights.
