The Laws of Prayer /The Blessings of the Shema (56)

1. The blessing of “Ahavah rabbah/Ahavas Olam” does not commence with the word “Baruch” as it is connected to the previous blessing. (Shulchan Aruch 60)

2. The order of the blessings over the Shema is not essential, and therefore even if he first made the blessing of “Ahavah Rabbah” and then made the blessing of “Yotzer or”, or even if he first said “Emes veyatziv” and then the other blessings, and even if he made some of the blessings after the Amidah, he has still fulfilled his obligation. Even if he made only one blessing, he has fulfilled his obligation regarding that particular blessing. (Shulchan Aruch and Mishne Berurah ibid)
