I don't think Kirk would have wanted pomp and circumstance either...and that is why Picard buried him as simply as he did. Perhaps Starfleet would have thought otherwise and sent for his body to be recollected and transported back to Earth for a memorial service as some of the novels suggested. As for salvaging the technology it seemed to me that the end of the film that is what they were attempting to do. It's true there is no on-screen proof but I seriously doubt that Starfleet would have wanted any hardware behind.
