Hi Parker,
airbnb will help you with a suggested price. I would recommend starting with a slightly lower price to begin with until you have a few review. Reviews are key and some research suggests the more the better even suggesting 100 good reviews are better than 4 stellar reviews. I would lower prices a lot on small gaps in booking to try and fill those up as you get closer to those dates..
I don't know your area that well but furniture quality is finding a balance between durability, cost and design sense. I would check thrift stores for dishes and silverware maybe cookware, Amazon or Homegoods/Marshals for cookware. Ikea for most furniture. I would spend a bit more on mattress, pillows and sheets. People will remember how comfy the bed is when leaving reviews. Good quality sheets will last longer. Remember you will be washing them a lot as you turn over between guests.
Remember to keep all your receipts to deduct on your taxes.
consider getting a keypad lock or lockbox for late night arrivals.
