fair business practices and jovial personality

Samuel Wilson was well-known for his fair business practices and jovial personality, so the townspeople referred to him as Uncle Sam. Eventually, his fair-dealing reputation won him a military contract to provide beef and pork to the soldiers quartered near Troy during the War of 1812.

I'd like to make sure the meanings of the underlined parts. Do they refer to the following respectively? Correct me if I am wrong. Thanks.

dealings/transactions

happy-go-lucky/happy
