I just did my plugs and putting the car up on ramps helped strictly because of the increase in height. I don't see how being under the car helped you on the drivers side. The support directly underneath those plugs looks like it would have blocked most of the access. Kudos if it worked for you though.
A big plus to the guy that said to remove the wire clips from the coil packs and rotate them 180 degrees to get the rears out. Helped me a lot!
P.S. It took me 2.5 hours and I had never done it before.
