He should know the names of his body parts If he wants clean fresh underpants on let him put them on underwear is cheap. As for the tp at school is in preschool or kindergarten? Most schools have urinals for boys with no TP in site so relax. As for after the bath let him dress in private he is 5 and can get dressed by himself. Everyone is unique and has quarts and things we have to work on some things done in private like changing underwear if there is a few drops of pee on them are personal things and no one needs to know.
Get through this year and worry about 14 when he is closer to that age. Good Luck!
