Hi Sharronica,
You need to get comfortable with the hurdles. Go over mini hurdles, then low ones and then keep moving them higher. Do lots and lots of walking step over drills, and look over the top of the hurdle to the next one, not directly at it. You're mostly having an issue with the inexperience. Stand next to your hurdles, 30 and 33 inches isn't as high as you think. It will come, and develop proper form
Stutter stepping is another issue. You need to get your step patterns down and execute the same thing between each hurdle, whether it is 3 step or 7. Most mistakes for novice hurdlers though is that they are actually too close to the hurdle at take off. Your maximum height should actually be behind the hurdle so that you are already coming down as you cross it.
