Best thing? Sign up for the orientation for the gym. You get a personal trainer taking you through all the equipment, and even though they can't specifically put together a training plan, you can get them to tell you what machines would be best for your goals, then have them take you through those machines so you have a good idea of how to use them.
People don't know about orientation a lot of the time and miss out on the opportunity to get a personal trainer... for free.
