Jeatyn,
I don't think the dog ears is a big procedure. I think it is a pretty minimal slice and re-sew. I looked it up once.
In terms of the nipples, from your pictures they don't look too long, just sayin'. My nipples are permanently erect (if you are saying hard). If I wear a tight thin shirt, they are noticeable.
On the whole, I do think that your chest looks really great. The pecs have filled out really nicely, you can tell you have worked on them! Personally, if I were you, I would get the dog ears fixed, but that is me. If it were an issue of a recovery for the same length of time and all for recovery, like you, I would hesitate. I really think it is a relatively minimal procedure, though.
