Yes, the 5.3, 5.7, & 6.0 rods should be the same length. The diameter of the 4.8 pistons is the same as that in the 5.3. The compression height is also within a couple thousandths so you should be able to use them with the 5.3 rods/crank. They should increase the compression ratio versus the stock 5.3 pistons. That said, you will still need to check all clearances (as with any engine build).
