Points 1 - 5 are all OK.
HP Laserjet 1020 is OK provided you have two things:
1. Printer driver for the Operating System you chose
2. USB cable from Laptop to Printer. Some older printers use an old connection = parrallel or Lpt1 and modern computers don't have this legacy port.

Digital camera will connect via USB and is OK.

The laptop overheating issue was caused by playing CPU & GPU intensive games. Also it was used in bed sometimes so it accumulated lots of dust fibres that blocked the cooling. I believe laptop manfactuers should use a dust filter or make it easy for the user to clean the fans/cooling area.
