From what I can see, your new dentist is right. Immediate placement and immediate temporization is a neat idea and nice when it works. But the pathology present on your initial CT would rule you out for immediate temp and load if not immediate placement with most doctors. Your buccal plate appears very thin. Resorbtion after placement resulted in your gum recession.  From what I can see, those implants are goners. 

Get a second opinion!  4 Bicuspid extraction is a very antiquated practice and should only be done when there is absolutely, positively no other option. It has a direct link to obstructive sleep apnea and craniofacial pain disorders later in life.  

It's impossible to tell what, if anything, broke during the procedure looking at that film. The spacing looks good to me. Unless you have a cat-scan post op and can post frames from it, there's not really a way to tell from 2D images what is going on three dimensionally. 

Mentalis strain is a significant indicator for ortho relapse as well as craniofacial pain disorders later in life. The best solution is to surgically release the mentalist either traditionally or with a laser.  It's a relatively simple procedure with quick recovery time. 

Yes, you are 100% correct. The standard is to have a wax up done and then an over-impression of the wax up is made and the injectable acrylic is placed into that mold and over the teeth. It looks like you have some pretty significant spacing between your teeth which makes the case a challenging one. I cannot think of a reason why a wax up would not be done. Additionally since you are not wearing temps that match the proposed final veneers there is no way for you or your doctor to make any sort of adjustments or changes before the final veneers are made.  The two labs I work with will not accept a case without a wax up being done at the start. 

My advice is do not accept anything that you are not 100% satisfied with. Do not let your dentist bond those veneers to your teeth without first letting you see them on your teeth with try in paste. And finally, do not allow your dentist to do significant drilling and adjustment on the veneers to "make" them fit or alter their appearance. A dentist experienced and highly trained in cosmetic dentistry working with a cosmetic dentistry lab will make a set of veneers that the majority of the time require no adjusting. The wax up and appropriate temps play a big role in that.
