Once again, the internal logic of the movie doesn't hold together all that well. Kirk was insubordinate and disobeyed direct orders on a number of occasions. He may well have deserved a commendation for original thinking (per TWoK), he may have deserved a commendation or medal of valour for his actions in saving the Earth, and he may have deserved a promotion. However, he also deserved at least one reprimand and definintely lacks the experience and self-discilpne to be in charge of an entire ship. Lets not forget, Olsen leaped before he looked and look what happened to him. Kirk needs more than that to be a good captain.
NuSpock doesn't display TOS Spock's reluctance to command. He is a higher rank at a much younger age (Commander at 26 instead of 36) and a first officer. Spock should really have been a lieutenant to Number One's Lieutnenant commander, catapaulted to command by her death or incapacitation due to injury (the latter would be better since we already have the death of the CMO as a method of promoting McCoy). This way he still receives a promotion to first officer at the end and it looks less like he has been shafted by Starfleet. I agree though, his lack of promotion is probably due to a desire to resign from Starfleet and his decision to sign on as Kirk's subordinate was probably due to Spock Prime's intervention.
If they had made Spock lower rank it would indeed not have been necessary for Kirk to be a full captain. However, it's almost a certainty that he would not have been awarded the Enterprise. Personally, I would have found it more satisfying if Kirk had been given command of a smaller vessel and finished the film with a traditionally cocky boast that he'd be back on the Enterprise before they knew it. Hell it could even have opened up the possibility of a tv series about his early career on the smaller ship with some new characters (I'm not such a purist that I couldn't cope with Kirk being re-cast for TV but whatever).
