That's a good list for a reliable rig.
Get an all aluminum radiator. The plastic models seem to fail at the most inopportune moments. I have a 3 core made my Champion. It's been in my Explorer 3-4 years. One less thing to worry about.
ABS delete is fairly easy with the 1st Gens. Removal of that giant ABS pump leaves room for a second battery. Pull the ABS relay and the dash light stays off. When I had to rewire the Explorer I removed what must have been 100' of ABS wiring. Left the sensor in the rear diff because it keeps the gear oil in.
What intermediate steering shaft are you going to use? I had a modified one out of a XJ in my rig for a few years until the u-joints fell apart. Went back to OEM, but have been looking for a alternative for a while that isn't stupid expensive. It's possible the SAS puts more pressure on the joints but I don't think so because the wheel is easier to turn post SAS. You might experience more vibration and feedback through the steering wheel. It's not uncomfortable, just different. The bigger the knobs on the tires, the more vibration. The rag joints soften that substantially.
