Welcome from Highland Park, Illinois, USA!
For ribs, try the snake method for coal arrangement (lots of videos on YouTube on how to set up, light and control on your kettle). The 3-2-1 method is a tried-and-true method for ribs (I use this myself - 3 hours in the smoke, 2 hours double wrapped in foil, 1 hour unwrapped (no smoke) and add sauce to set). For ribs, I like to put the rub on my ribs the night before and let them get friendly in the refrigerator. Just before I put the ribs on the grill the next day, I add more rub to cover any spots that might have worn off.
Based on what folks have shared with me and my own personal experience in smoking with my kettle: 1) invest in a wireless thermometer so you know what the temperature is inside the grill; 2) target temp is a range - not an exact number; 3) try different recipes - I was shocked at the variations out there and what fit my palate best (check out Malcolm Reed's YouTube videos as I think he makes the bbq process very simple); 4) don't get stressed out - have fun. It's a 5-6 hour cook, so get comfy.
Good luck! Can't wait to hear how things go the next few times you smoke!
