The first is on this site in the list of idioms: Penny wise, pound foolish - Idiom Definition - UsingEnglish.com

I'm not sure whether I'd call the second 'idiomatic'; it's more of a quotation (I think). It means that it is only when you want something that you think about ways of making it happen.
