I didn't understand all that you were trying to do so here are some general pointers.

Korn shell supports arrays. You could pull your data in seperate arrays for node, cust and mb then do a loop on the array counter.

while loops often work better than for loops.
i=0
while [ -n "$cust[$i]" ]
do print "$node[$i] $cust[$i] $mb[$i]
   i=$(( i + 1 ))
done
