As a leader, you are given a job to be done and a set of people and resources to do it with, and your job is to coordinate things.
As "a complete neophyte," you're lacking the single most important attribute of a leader: knowledge of your team. The first thing I would do in your situation is to talk to each member of the team and get to know them. Learn their personalities, their strengths, (particularly their specialties,) and their weaknesses.
Once you've got an idea of what your team can do, as individual members and as a team, you should go after the job. Figure out what it is that needs to be done, get as much domain knowledge as you can cram into your head quickly, and start breaking it up into smaller parts. Hopefully you'll have at least one team member who's a domain expert and can help you with this.
After that, it's time to get to work. Delegate certain tasks to your team members. Contribute as much of your own effort to the work as you can without interfering with your responsibilities as a coordinator--this will help you earn the respect of the team.
And remember that your main responsibility is to coordinate things. You're not a general, barking orders to the grunts that are to be obeyed instantly and without question; you're the guide for a group of skilled professionals, a specialist who specializes in the big picture. Your team members have their own specialties, so be willing to listen to their ideas and consult with them. Make it clear that they're free to come to you with ideas and concerns, but also that as the leader, the buck stops with you. Sometimes you'll have to make a decision between two seemingly-good alternatives, (or two alternatives that different team members each think is good,) and the final decision--and the responsibility for it--rests on your shoulders.
Basically, stay out of the way as much as possible and try to make sure your team members are able to do the best work they can, and they'll love you for it.
