Does this sound right for the first one? The Wrap-Up List by Steven Arnston. The main character is Gabriela, she receives a letter foretelling her death and must complete a list of wishes before she dies. And the cover is red.
I am less certain about the second one. One possibility is Friend Is Not A Verb by Daniel Ehrenhaft. Emma is the best friend of the main character, Hen. They is a band involved. It is not clear if she ends up at Julliard or not. Unfortunately, Omaha Public Library does not have a copy of this book.
Hopefully at least one of these is right, but if either of those don't seem right, please let us know and we'll look again.
