The secret to moist chicken is DON'T COOK IT TOO MUCH! Seriously--overcooked chicken is dry and hard as a rock. Bleh.
Thaw out your chicken, trim it, then slap it in a pan that's been sprayed with Pam or something like that. Cook at 350 for 35-40 minutes, then take it out and let it sit on the counter for a few minutes before serving. Food will continue to cook for a few minutes after you take it out of direct heat. If you're nervous, cut into the thickest part (generally near the middle) and see if it's done all the way through. This will give you cooked chicken. (I'm assuming boneless/skinless here. Cooking times will vary with the addition of bone/skin.)
As for what to do with it...there's lots of possibilities. Pour your favorite spaghetti sauce over it, add veggies if you want. Add BBQ sauce. Marinate it first. Sprinkle with any available spice mix. (Emeril does nice ones, as does...what...McCormick? In the spice aisle at the grocery store they're generally underneath the big individual spice rack.) Add potatoes/parsnips/carrots/onions and a bit of chicken broth then cover the pan with foil for a "chicken pot roast" effect. Or cook the chicken plain, take it out, and THEN add to it. Play with it and have fun.
