Question

I have this loop at the same it will count the output:

while ($wp_query->have_posts()) : $wp_query->the_post(); $current++; $current2++;

Answer 1

If I understand what you are asking here, I think you want to alternate your divs with'first' and 'second' classes?

As such, you can use the % modulo operator (see http://php.net/manual/en/internals2.opcodes.mod.php)
