Good advice. One easy mod is to loosen the mounting bracket on the tach and swivel it so that your shift rpm is pointing straight up at the 12 o-clock position. This way you don't have to figure out where 5,500 or 6,000 is...your peripheral vision will see the tach needle standing straight up and you can shift from there. Allow for a 200-300 rpm buffer to your rev limiter (i.e. if you are running a 6K chip, set the tach's 12 o-clock position at 5,500). Short shifting a couple hundred rpm will not hurt your ET as bad as an over rev.
