I don't fully understand what you mean by:

I need to read about expansions!
Fortunately this stuff is pretty well documented. I'd start with Shell Expansions, it's probably best while reading this to have a shell handy and try out the different expansions/substitutions mentioned with something like the pparm script posted above. Ensure you understand why they shell works the way it does.

For example word splitting occurs before pathname expansion, so when a file containing white space is expanded it wont be split.
Parameter and variable expansion occurs before word splitting so variables with white spaces are split:

Code:
$ ls
 jason_expand   pparm  'test with space'
$ ./pparm test*
Param 1: test with space
$ VAR="test with space"
$ ./pparm $VAR
Param 1: test
Param 2: with
Param 3: space
$ VAR=test
$ ./pparm ${VAR}*
<work thru the manual and decide what will happen here before trying it>
