Welcome! I'm sorry that you have reason to be here, but I think you'll find the people have a lot of information and are very helpful. I'll try to answer some of your questions.
According to Newsweek (I think), the best places to treat cancer are; Memorial Sloan Kettering in NYC; MD Anderson Cancer Center in Houston; Mayo Clinic in Rochester; Dana Farber (Boston?) and several others. You might research cancer and hospitals on google.
Surgery is considered to offer the best option for cure or long life without cure. Sometimes, depending on the stage of the cancer, surgery is followed up with chemo and/or radiation. My understanding is that radiation before surgery isn't an optimal situation because radiation damages tissues and makes healing from surgery more difficult.
Sometimes people have chemo and radiation before surgery in hopes of shrinking the tumor before trying to remove it. The sooner that you dad can get rid of the tumor the better, so hopefully, he won't need other treatment first.
If he has surgery, then the next problem is to keep the cancer from returning. Frequent CTs will be needed.
I had a 3" tumor in my upper right lung (URL) removed in June 2003 and had chemo following that. The doctors seem to think that in Nov. 2004 I had another primary tumor. Had surgery and chemo again and have been cancer free since then. In June 2010, I'll be a 7 year survivor.
We have a number of people here who are longg-time survivors. The longest being a woman from MN who is a 14 year survivor.
Let us know how things are going with your dad and what treatment plans are decided upon.
