My First Kettle Grill

I picked up a 22 inch on FB Marketplace for $50. The seller was nice enough to throw in a chimney starter, 16lb bag of coal, lighter fluid, and 4 bags of wood chunks. Seems to be in good shape. I plan on cleaning it and grilling a whole chicken today. Are there any upgrades that are must haves? I was thinking about upgrading the ash catcher to the same one found on the premium models. Anything else I should consider?
