I also keep seeing the use of my $thing = $q->param('whatever'); but am having trouble searching for it as I do not know what name it goes by...

This is the OO ('Object Oriented') interface to CGI.pm: 

use CGI;
my $q = CGI->new;
my $value = $q->param('name');

Roughly equivalent to: 
use CGI;
my $value = CGI::param('name');

except the OO way rends to be more flexible and earsier to modify (eg, you could write/use a module that inherits from CGI, by modifying only the 
use
and 
new
statements. There's other reasons, but it's too early.
