It's important to realize that using too much rudder will bleed E very fast as well. You mention being worried about over-using your ailerons, which I doubt is a real issue. To keep E-loss to a minimum keep an eye on the slip indicator, and "step on the ball". If the ball is centered, all is well. If it's a bit to the right, right rudder is neede to bring the ball back to center.
Using the rudder to bleed E isn't always a bad thing, just be wary of over-using it unintentionally.
