her-2/neu overexpressed and confused

Before I start my question I just want to express my wishes and respect for all that communicate on this site. I am sooo impressed with your bravery and consideration. My wife (41 yrs old and otherwise very healthy)was diagnosed with stage IIIA bc (2-3 cm tumor in left breast with 7 of 16 axillary nodes positive)in 10/03, had a mastectomy and has now had 3 of 4 AC treatments to be followed by 4 Taxol, radiation, and then hopefully herceptin. Chemo schedule is dose dense (every 2 weeks). I'm nervous because although her Oncologist is a caring man I am concerned that he is not familiar enough with all that is on going as it relates to bc and he is not very aggressive. It is through my encouragement that she is on dose dense and he is looking into herceptin. I have read all of the recent messages and want to ensure all is done to prevent a reoccurrence. He is of the mind set that trials are unproven and you want to save some bullets in the gun in case. I therefore have 2 question...am I looking to be to agressive too early and is there anything else out there that anyone would anyone recommend looking into (already looking into the Washington vaccine)? Thank you
