It looks like you've got just about everything you'll need, but I'd go a step further and add a charge line kit, part # RM-156-25. Your braking system will draw power directly from the battery, so it would make good sense to use the 12-volt supply from the motorhome's 7-way to keep the battery topped off while towing.
The power for the taillights on the Focus will come directly from the motorhome while the vehicle is being towed, so the diode kit included with the # RM-9243-1 combo wiring kit is all you'll need for the lighting.
I've linked to installation videos for the base plate and the charge line kit.
