I did my spark plugs today and was able to get a couple easy ones off by coat hanger and a couple by hand. The passenger rear was actually one of the easiest ones to pop up for me. I used a small pry bar with leverage like this and it easily popped right out. The whole job took me about 2 hours so It can definitely be done in a half a day.
The pry bar I used is the smallest one in this set:

hope this helps anyone who attempts this in the future.
