I'll advocate weights. Your skating time will be just as good as running. In addition to the weights make certain you're skating at least 2-3 times a week.
Squats are just as good as wind sprints and they'll work your entire body. Do these religiously. Don't ignore your upper body strength. You'll need it if you're up against the boards fighting for a puck.
Keep in mind... I expect that your lines will be changing out every minute or two so when you're on the floor, it's a sprint. So you're game is explode, recover, explode, recover, explode... it's not a marathon.
