Highly unnecessary for this job.
Just click the shifter into the highest gear, releasing all cable tension. Obviously allow the derailleur to shift into the highest gear. Turn the barrel adjuster all the way IN (clockwise). Disconnect the old cable, and remove it.
Guide the new cable through, pull it firmly through the anchor bolt, and tighten the anchor bolt.
Personally I've found the Shimano Shadow derailleurs VERY easy to adjust. If you pull the cable through firmly, you should only need one or two turns of the barrel adjuster to get it shifting smoothly. On one or two instances I've actually pulled the cable through firmly enough to get the tension spot-on the first time.
A cable-puller is one of those tools which while being nice and handy to have, is fairly unnecessary for things like derailleurs.
For things like brakes and whatnot I understand that, as you need to hold the brakes, pull the cable through, and tighten the bolt all in one. But for derailleurs, it's really not needed, as the derailleur holds itself in place.
