it looks like a minor repair would take care of the extra skin flap I see on the left labia. Probably a simple office procedure by a qualified Gyn specialist. 

It looks like the left side had a wedge type labiaplasty that separated. This could be repaired with a revision labiaplasty and would be unlikely to happen again if properly done. I recommend a gyn specialist for evaluation and treatment. Some plastic surgeons have expertise in this type of procedure too. 

Based on the pictures,  I can't see anything that looks abnormal. The "bumps" are part of the hymenal ring and vary in appearance from woman to woman. If you are concerned, then I suggest seeing a gynecologist for reassurance and a regular check up. 

It looks like the picture shows the hymenal ring at the vaginal opening. This is normal and looks a little different in everyone. 

It sounds like your surgeon has already planned to repair some weak support in the pelvic floor and vagina. The hysterectomy would not typically be cause for loosening of the vagina. In fact, at the time of hysterectomy, we usually take advantage of the opportunity to improve pelvic and vaginal strength by tightening the "ligaments" and supporting structures of the bladder, rectum and vaginal opening. A sling is often recommended if there is significant urinary stress incontinence.
