RE: Grip strengthing
deads first man, always always always, generally you should be lifting more weight on deads so fresh grip will be most benefical here, but deads is the most anabolic exercise there so do it first. You shuold find that your grip is strong enough to do chins and rows afterwards, if not then you can use wrist straps to aid yourself.
Get a captain crush, wrist curls, practise holding big weights. Just build it up like any thing else.
