What are some of the most useful idioms to learn?
You may flip through the list of idioms given on that site, here: English Idioms and Idiomatic Expressions - UsingEnglish.com
As a matter of fact, my own belief is that an idiom is a piece of culture, so wherever you go where people speak English (the USA, the UK, Australia, the Republic of South Africa, etcetera etcetera) you'll find it specific.
But maybe, there is a list of most used idioms.
