How do I find data on total returns for stocks, bonds, and indexes?

Go to WRDS on the library database page, and choose CRSP.  Daily and monthly stock files and indices from December 1925 --  The files are updated annually.
Also look at the book, Stocks, Bonds, Bills, and Inflation by Ibbotson Associates. It is in the Ford Library reference section under call number HG4915 .S6.
