Re: Question of 'amount of' & 'number of'
You have got it right. We use "amount of" or "amounts of" before uncountable nouns. We use "number of" or "numbers of" before countable nouns. Whether or not we pluralize "number" or "amount" depends on the sense of the sentence, but there is little difference between "a large amount of money" and "large amounts of money" or "a large number of vehicles" and "large numbers of vehicles".
