Or put another way think 4 layer boards with power and ground planes.

For high-drive outputs, my favorite is the 74AC541 octal bus driver, which is very nice for paralleling outputs through small series Rs. If you look at the pinout, you'll see why.

BTW with any of these high-drive circuits, it is essential to provide good bypassing of the supplies, and be sure of clean low impedance pathways for the signal output and return currents.
