In the prayer to Sai Baba in Chapter 26, what specific things does the author ask for? It seems like a very deep surrender.

The prayer in Chapter 26 is indeed a profound act of surrender. The author asks Sai Baba to take away his body-consciousness, stating a need for neither the knowledge of pleasure nor pain. He lays his ego, or "me-ness," at Baba's feet and asks to be moved according to Baba's will, like a puppet. He also prays for his restless mind to find peace at Baba's feet and for the grace to personally experience spiritual knowledge, as mere words are not enough. This series of requests, as detailed in Chapter 26, illustrates a complete and total surrender of personal will and identity to the Sadguru.
