The steps on your list look right. I usually spray some penetrating oil where the bar goes into the lower control arm and also pull back the boot at the rear of the bar and spray in that area too. I use a lead hammer to smack the sides of the bar where it attaches at both ends to help get it loose after you have unloaded it. If you plan to save the bar you will want to try not to nick the surface of it. The correct tool does make a big difference on stubborn bars.
