I mean the run line variables ($1 $2 etc.). And I was

When in doubt, use echo $some_var_here or better yet

echo " >$some_var_here<" to detect any leading/trailing white space.

I still have to figure out how to get the
full path and name of the script.

You already know how to get name of script.

As you have seen, ./script_fn, bit you, and if you look at $PATH the
script could be in one or more places.

You can test first character for . and if so use $PWD.
Then run result through type. Here is a quick untested kludge

_exe=$0
_char1=${$_exe:0:1}

if [ "$_char1" = "." ] ; then
_exe=$PWD/${$_exe:2}
fi

set -- $(type $0)
_fn=$1
_dir=${3%$_fn}

echo $_fn $_dir
.
