Plato's underlying attitude toward the body is that it is temporary, and something to be cast off. The body is not the person, it is a shell. The actual person is what resides inside the body until separated by death. Overcoming the fear of death and feeling like death could actually be a good thing - a new adventure - is a large part of Plato's focus. Whether he is correct in this cannot be answered, because there is no factual proof of whether or not a person lives on after the body dies. Many believe it does, but there are plenty who believe it does not. It is also not possible to say whether Plato is correct in assuming that only philosophers who have conquered their fears and desires are virtuous. Might not a person who does the right thing in spite of his or her fear and desires be virtuous, as well?
