tmutamaenda the biggest issue to worry about is the water damage. Anytime you try to charge, sync or start it you are increasing the chance of a short circuit. Keep the battery out of it and fix the water damage first.
If you do not have access to an ultrasonic cleaner, I suggest you get some 90%+ isopropyl alcohol and a soft brush. Disassemble your Note by using these guides Clean your board and all the other parts with it. Use this guide to see how to properly clean it. It was written for an iPhone but all the points a re still pertinent to yours as well. Remove all the EMI shields to clean under there as well. Once you have it cleaned, check all the components on the board. Make sure none are missing, or otherwise damaged. Make sure all the cable ends and connectors are also cleaned. Then reassemble, replace the battery and re-evaluate.
