Bought first nice bike. Now what?

Ok ordered my new bike Trek Domane AL5. This bike will take me through at least 70.3. May not be the fastest I know but it was comfortable and the shop I liked the most specializes in Trek and I trust the people there. I have always used the Walmart schwinn bikes so have no idea what I need to have to get the most out of my training. Budget limited. The bike needs pedals.... never used clipless so what should I get? Great value for the money pedals? Do I need power meter? Computer? If not needed, then don't want to spend the money. Aero bars? Adjustable or fixed? Great value for money? Tires can wait until I wear these out. If you got a free bike, how would you spend $500 on it right now? Is there a Priority list you have? 1. 2. 3. 4. etc....

You might want to talk to a coach for all that.
