I get my plugs and wires done in just over an hour... I do it from the top. Not that hard, but I'm tall, and you mentioned you're short. I use the Mobil1 0W30 in mine. You get the higher grade true synthetic. The book calls for 5W30. I don't even use 10W oils in my vehicles that call for 10W. I use 5W30 "Extended Protection" in the 1981 Regal. With Mobil1 the Zero weight oils, and the grades marked "Extended Protection" are true synthetics.
