Hi Sam
I can't help with most of your questions however, I had 4 treatments of AC and 12 of Taxol. AC was every 3 weeks compared to every 3. I had more treatment than I actually needed but it was my decision (I couldv'e had only AC). As the Breast Care Nurse said "you have made the right decision. You have done everything that you can and if you get cancer again at least you know that you did everything you could do in the first place". That made me feel a bit better for my decision.
As for a port, I would highly recommend one. Mine was in my chest and I loved it (I actually hated having it in my chest but loved it for my chemo). I have had mine removed now, but it I ever needed chemo again, I would definitely get another port put in.
Good luck.
Sally
