Hi Pete, welcome! I hope I can answer your questions. First of all, from what you write, it doesn't seem like a critical situation. Doctors are looking for fasting results to be under 100; this is considered 'normal' or non-diabetic. In answer to your questions, this is what I think:
1. He might give you a prescription for metformin (the generic Glucophage) which helps the body metabolize carbohydrates. If he does, I would imagine that he would also prescribe a blood sugar meter so you can monitor your own blood sugar at home. Then, I would expect that he would want to see you sooner than six months. Or, he might just give you a diet guideline and tell you to come back at some other time.
2. Metformin is normally the first choice for someone who's a straight-forward type 2 at the beginning. It's very cheap and usually on the list of the $4/month or $10/three months at most pharmacies these days.
3. Side effects of metformin can be problems with your stomach: acid-like feeling and or diarrhea IF especially you eat a lot of carbs. It's best to take this with food.
4. Other information that you need to know, I'll explain later!
5. Questions for the doctor? I guess that depends how he views treating patients new to blood sugar problems. See below.
My comments: Doctors seem to have different ideas about patients whose blood sugar is like yours (and mine) because it's not critically high. Some doctors would tell you to watch your diet, lose weight, get some exercise, and go back to see them in six months. When some say 'watch your diet' they might hand you the American Diabetes Associations handout. However, in my opinion that will keep blood sugar elevated. And this is because:
Different doctors and medical associations have different ideas and parameters for what blood sugar ranges we should have. A non-diabetic's blood sugar will rarely get over 140 and that would only be after a meal heavy in carbs like at Thanksgiving (potatoes, yams, gravy, stuffing, pies - all carbs). Cutting way down on carbs will help keep your blood sugar lower. Some doctors will be satisfied if you keep your blood sugar 'lower' than it is now but in reality that would be higher than a non-diabetic's.
There are many kinds of drugs for diabetics that work in different ways. Some help with metabolism. Some help the pancreas produce more insulin. Your needs determine what meds (if any) are necessary. In difficult cases, an endocrinologist is the specialist to see.
If there is diabetes in your family, if you are overweight and not physically active and if you eat a lot of carbs, then it's very common to find high blood sugar. Some people have been successful at your point in controlling their blood sugar by losing weight (but I have no idea if you need to), engaging in regular, sustained exercise and cutting way down on carbs.
I always recommend The Diabetes Solution by Dr. Richard Bernstein because it is a book that explains the disease (types 1 and 2), medications, lifestyle, testing and food. It even has recipes.

I know this might be a lot to chew on at one time, so take one bite at a time. And ask any questions you want!
