Do grip training once a week. Always. 5-6 sets of various things, do pinch gripping with plates and other things. Search the net for grip training and you'll get an idea.
And only do reverse grip curls for forearms. The grip training will take care of the rest.
Other than that: Focus on the big lift: Squats.
Make an effort to get a good lifting technique, all the way down where your hammies LITERALLY touches your calves. Start off with a lighter weight, don't worry bout the weight, just make sure you know what the hell you are doing when you are squatting.
And oh, don't use a belt when squatting. You want to get your abs involved.
