Is this Japanese sentence right?
Is this how you say: 'Hello, my name is Ethan' in Japanese?

こんにちは，私の名前はイーサンです。

Just want to make sure I've got it right.

Also can someone please explain the difference between watashi (私), boku (僕) and ore (俺).

Answer

俺 is very casual form which should be used among friends. This is used not only old men but also youngsters. 僕 sounds casual and should not be used in business. I recommend you to start from 私 to meet someone for the first time, 僕 after you become a friend with someone. 俺 should be used once you got at native level. If non-native spearker who has a smattering of Japanese uses 俺, it sounds very weird.
