Hey wow!
Thanks for help. I appreciate the suggestions/tips a great deal. I took most of the advice offered up here, and came up with the following: 
open FILE, "$ARGV[0]";
while (<FILE>){
    if (/^%%EndSetup.*/){
        $doctitle = "Unknown Document Title" unless defined($doctitle)
+;
        $pagestate = "Simplex" unless defined($pagestate);
        $pagesize = "Letter" unless defined($pagesize);
        $copies = 1 unless defined($copies);
    }
                                                                      
+                                                                     
+    
    # Document Title
    unless (defined($doctitle)){
        chomp ($doctitle = $1) if (/^%%Title: (.*)$/);
    }
                                                                      
+                                                                     
+    
    # Duplex or no...
    unless (defined($pagestate)){
        $pagestate = "Duplex" if (/^%%.* \*Duplex Duplex.*/ || /^\[&l1
+S/i || /^\[&l2S/i || /DUPLEX=ON/);
        $pagestate = "Simplex" if (/^%%.* \*Duplex None.*/ || /^\[&l1S
+/i || /DUPLEX=OFF/);
    }
                                                                      
+                                                                     
+    
    # Page Size
    unless (defined($pagesize)){
        $pagesize = "Letter" if (/^%%.* Letter/ || /^\[&l2A/i || /PAPE
+R=LETTER/);
        $pagesize = "Legal" if (/^%%.* Legal/ || /^\[L3A/i || /PAPER=L
+EGAL/);
        $pagesize = "Tabloid" if (/^%%.* Tabloid/ || /^\[&l2000A/i || 
+/PAPER=LEDGER/);
    }
                                                                      
+                                                                     
+    
    # Number of copies
    unless (defined($copies)){
        $copies = $1 if (/^%%.* numcopies (\d+).*/i || /.*QTY=(\d+).*/
+);
    }
                                                                      
+                                                                     
+    
    # Number of Pages
    unless (defined($pages)){
        $pages = $1 if (/^%%Pages:\s+(\d+).*/);
    }
}
close FILE;

I got parse times down from 90 seconds to 1-2 seconds on a 42MB test file. I appreciate the help a great deal.

Y'all are awesome.
