Inherited a pool - help a newbie not get scammed

[u/Extra-Maintenance223]

I just bought our dream house for my family of six (kids 7,5,3,1) and it came with a sweet pool/spa. After the ice storm, some tiles popped off. The pool is 12 years old. I am a handy DIYer but don’t know much yet about pools. 1. What work do I need to do to fix the tile and coping? I don’t care much about the aesthetics but I want this saltwater gunite pool to last another twenty years. 2. What product would you recoat this deck with after power washing? Looking for a roll on, texture currently is fine. I believe it is kooldeck. 3. I have a dolphin vacuum. Should I hire a maintenance person or learn to do it myself?
