For the rod knock, I'd be looking for bearing material and/or metal shavings in the oil. For the piston skirt, I'd be looking for large chunks of piston skirt in the oil. Dip stick is an okay way to check for shavings or bearing material. Dropping the oil pan and visually and physically inspecting the connection rods is your best bet for determining rod knock.
The first thing I would do is take off the torque converter cover plate and bellhousing brace to inspect your flexplate and associated bolts to the torque converter. If that looks okay I would do a compression test on all the cylinders. If that checks out okay I would drop the oil pan and inspect the connecting rods, cylinder walls, and underside of the pistons.
