I'll second what Ilene said. When I started (or re-started, this year), I just started with trying to get the most out of the skating I was already doing 3 days a week. Later, I added in jogging/walking, working my way up to jogging 30+ minutes. For a while, that was a good workout for me, but then it seemed to get too easy and my weight loss seemed to be stalling out. I started spicing up my jogging workout by doing some stairstepping, pushups, crunches, and the like, while jogging in between. I didn't lower my calories, though, and they're about the same as yours or a little higher. Not sure if it made the difference, but I started losing again that week. Recently, I switched to weight lifting, followed by jogging, those 3 days a week, still with the skating the other 3 days (which for some reason, always kicks my butt and never gets "easy"). I figure, all I can do is eat well, eat enough, drink my water, and make every workout count. So far, that strategy is still working.

Best of luck to you! Sounds like you're doing well so far!
