The feat Quick Reposition (Advanced Players Guide)allows me to make a full attack action, then reposition my enemy in place of my first attack. Now, would repositioning my enemy into a flanking position allow me to gain flanking benefits on my second attack?
That is not how it works. It allows you to substitute the maneuver in place of an attack roll, not get a full attack, and treat the enemy as he was flanked the entire time.
When you get to do something in place of an attack that other thing is done instead of the normal attack. You don't get both.
Benefit: On your turn, you can perform a single reposition combat maneuver (Advanced Players Guide 320) in place of one of your melee attacks. You must choose the melee attack with the highest base attack bonus to make the reposition.
Basically when you make your first attack roll you can use it as a combat maneuver check to reposition him. If he is in a position to be flanked then you get the flanked bonus for your remaining attacks.
Another example is making a trip attack in place of a normal melee attack if someone provokes an attack of opportunity from you.
Aight, got it. Thanks a bunch man.
