Moving your bindings forward will not change being "a back seat rider," but in may improve the performance of your skis. As pointed out, you appear to have a technique and not an equipment issue. If you want to try something fairly easy and cheap that may be helpful, see if you can adjust the forward lean on your boots. Many boots come with a preset upright stance that can put you in the back seat when you bend your knees. Adjusting them to give you a more forward flexed position could help keep your weight on the front of the skis where it belongs.
My Dalebellos came with an upright position and two wedges that could be inserted to increase the forward lean. I need the big wedge, while my wife uses the smaller one, and some people like them with no wedge. If I had just skied them out of the box I would have no wedge and be in the back seat myself. You need to have a boot that functions with your body type and skiing style, and experimenting with forward lean is usually an easy thing to do. Almost all top line boots have forward lean adjustments. Cheaper model boots may have a fixed forward lean, but if you talk to a good boot fitter they can usually modify them for you.
Something as simple as loosening the top buckle a little will allow you to stay forward more easily. FWIW, I have several pairs of skis with adjustable bindings and have found that I prefer them all back from the factory line, as opposed to forward.
