for your first question (exporting variables without our, one option is explained by jarich above. A second option would be to fully qualify your exported variables with the package name, as in:

package I_am_an_example;
use strict;
use vars qw(@EXPORT @ISA);
use Exporter;
@ISA='Exporter';
@EXPORT=qw($jimmy $bob);
$I_am_an_example::jimmy="White";
$I_am_an_example::bob="Hope";
1;

Your require does not work because with use strict;, you need to declare the scope of your variables. To pull in the incl.pl as above, you would do:

use strict;
use vars qw($test1 $test2);
require ('inc.pl');
print "$test1\n$test2\n";
