Okay, well push-ups are mainly using your triceps as any pushing uses triceps, and pulling uses biceps. You could try tricep dips on your stairs, or even using the floor. Also, keep practicing with "girl push-ups" until you're strong enough to do regular push-ups. As for sit-ups, I'm not sure why you're not able to do any?
