I don't like the pickle forks. I don't think they work that well and they usually tear the ball joint boot to hell. If you have a Harbor Freight near you try this, it works great. Most auto parts stores will have it to but you can get it much cheaper at HF.

You will more than likely have to replace the ball joint boot. If you want to replace it with oem the p/n is MB808555.
If you are going to remove the hub/spindle then IMO it is easier to just leave both lower control arms attached at the ball joint end and unbolt them from the subframe. If you do this just place a jack under them so they don't suddenly fall and tweak the ball joints.
Good luck.
