1. if your not particularly pre-disposed to fat storage then I don't think having a mcdonalds is too bad occassionally. BUT of course its better to eat clean.

2. Sure, oatmeal is a good low GI carb source and will promote growth.

3. Again, weight gainers aren't as good as real good, and often contain a lot of sugars (which may lead to fat storage and sub-optimal growth), but again, if your not particularly predisposed to fat gain they might suit you fine. Its also true that there are some weight gainers around which aren't that bad, Extreme's performance mass is an example.

It sounds like you already have a good protein base sorted out. Perhaps your doing too much cardio and not taking advantage of all the calories you are consuming by burning them off too soon, or maybe you aren't consuming enough calories in terms of low GI carbohydrates and fats.

Could also be worth investing in some creatine monohydrate to push things along.

My general advice to you is to cook up a huge batch of good carbs in the morning, like brown rice, and bump your meals up with that carb on each meal. Whereas before you maybe would have had 1 chicken breast with 1 cup of rice, try adding an extra cup of rice to it for example. I think carbs might be the key to you gaining weight.

all the best
