Here is an update,
Finished up bleeding the brakes, for the 4th time, today and now she stops on a dime

... okay I am exaggerating a wee bit. I is tough to stay seated without belts though so, huge improvement. The brakes still feel a bit spongy to me but it is a marked improvement from where they were. So, here is what I did to address.
There were several items that had to be re-addressed.
1st: Check valve and grommet. Check valve seemed to work okay but I decided to replace it anyway. The new brake booster came with a grommet that was a tad too large and was letting air by it. I replaced with a Toyota grommet and this seems to have resolved the somewhat hard pedal. The one item here that I am not sure about is when I test it by letting it run, holding the brake down, and shutting it off. The FSM says it should take 30 seconds or more to rebound. Mine starts in 5 to 7 seconds.
2nd. I did the LSPV delete as mentioned earlier in this post. Well I bungled it. The o-ring I used did not hold and, as a result, I had a significant leak. I fixed this by using copper washers instead of the o-rings. Easier and obviously less at risk of failure. See pictures below.
3rd. I had never heard/seen this before. When bleeding the passenger rear caliper, the fluid came out almost as a gel. Thick, about the consistency of nectar.

Any ideas of what caused this. Air entrainment?
So after replacing all soft lines, all calipers, master cylinder, brake booster, rotors and pads and bypassing the LSPV, the brakes are the best the vehicle has had since I owned it. I still would like a firmer brake but not sure how I can attain that apparently lofty goal. Without further ado, picks.
Test of the copper washer to see if it seated properly.
All the parts I used.
Stainless hardware and copper washer being installed on the bottom end.
I used 4 copper washers inside the LSPV as a spacer. I could barely get a socket on the nut with a single washer and was not comfortable with that. I don't like stacking but, did not see a practical alternative.
Note that there is a rubber grommet that goes in this location that is removed. The area around it is raised a couple of MMs or so. I added a SS lock washer as well. I did not trust nylocks in the brake fluid.
I used a jam nut as well. I just don't want this to fail.
