。
She gave me not only information but also advice.
Literal
She [topic-は] information [not only-ばかりでなく] advice [also-も] me [to-に] gave.
The ~ばかりでなく...も pattern ('not only X but also Y') emphasizes that she went beyond one type of help. くれた (from くれる, 'to give to me') marks the giving as directed toward the speaker. 情報 (じょうほう, 'information') and 助言 (じょげん, 'advice') are both formal-register nouns.
