It probably won't make a huge difference, but you can skip the "set" command, I believe.
varname=`blah-blah...`
is a valid variable declaration.
Typically, I will have a development machine that I test on, and when confronted by issues running a specific script, I use the system log to determine why a script is failing.
The "logger" command can be used effectively:
logger "Software update status: $applesw"
...
loggedin=`who | grep 'console' | awk '{print $1}'`
logger "Users logged in: $loggedin"
Actually, you appear to be using command line substitution in setting up your variables, but you are using double quotes instead of the backtick `
