Are these good scores for SAT II Literature and US History?

I got a 730 in literature and a 780 on US history. I feel very confident on my US history one, but for lit I'm not so sure. If I plan on applying to ivy league and top tier private schools, should I try to retake lit? Also, I will be taking the SAT for the first time in october and the spanish with listening and maybe lit again in november. If I dont score at least above 2000 on the SAT the first time, should I scrap taking the Spanish test and retake the SAT? I'm an incoming senior by the way.
