Literal
She [topic-は] kindly [emphasis-も] me [to-に] good advice [object-を] did-for-me.
助言をする (じょげんをする) is the standard phrase for giving advice. 助言 combines 助 ('help') with 言 ('words'), literally 'helping words.' The に marks the recipient of the advice. The よい preceding 助言 is the literary/formal form of いい ('good'), giving the phrase a slightly elevated tone.
