I use a Craftsman 1/2 in drive deep socket #47532 to remove the injectors. it works fine for me and deep enough for the injector to fit all the way in.
replace the heat shields when you remove the injectors. I have reused mine when I didn`t have new ones on hand and seemed to get away with it

. don`t recommend it, think I was doing it under a shade tree

.
use the proper return line from the injectors, and the last one has a plug in it. I reuse the plug, just slice the rubber and replace it in a new piece of hose.
That`s a beautiful car you have, I love the CD`s, not many around. just don`t drive it in your winter salty conditions. get an old Ford for your beater
