Your total cholesterol and LDL levels fall into the “high” range. Not at all the same as “isn’t too bad.” You also don’t mention your triglyceride levels which are just as important.
The changes you mention are good, but you don’t mention dinner at all, which is probably your biggest meal of the day. Nor do you mention snacks. A few donuts, just for example, have a huge amount of fat in them.
If you’re serious about attacking your levels through diet, then you have to rethink you’re whole way of eating. Every food you put in your mouth has to be examined for its fat, saturated fat, and trans fat amounts. You also need to balance the rest of your diet with the whole grains, lean meats, and lots of fruits and vegetables that everyone recommends.
What’s important is that you understand that this is a lifetime change. Eating oatmeal every morning will grow boring very soon. Salads at Wendy’s, same thing. Besides, salad dressing is pure fat and those salads are topped with cheese, bacon, almond slivers and other high fat items. You need to find an enjoyable and satisfying low-fat lifestyle that you will be able to stick forever, without constant cheating.
Increasing your knowledge about nutrition and calorie, fat, carb, sugar and protein counts in foods will be enormously helpful.
If you can cook for yourself, do so as much as possible. Make your own lunches. Fast food restaurants are traps. You can, if you know enough, find low-fat items there, but there are few of them, they are the worst tasting foods on their menus, and they load them up with high-fat traps to make them edible. I know how convenient it is to have others do all the cooking, but it’s very tough to go low-fat on restaurant cooking.
And there is a genetic component to all this. Even a low-fat diet may not be enough. Some of the statin drugs may be necessary to get your numbers down.
It’s not easy and I had to learn the hard way how necessary it all is. When you haven’t followed a regimen of proper nutrition, exercise, and avoidance of other risk factors, the change is major. You don’t say how old you are, but being older not only increases your risk but makes any change more difficult.
It can be done, though. I’m proof. And my reward was that my doctor just increased my dosage of Lipitor because it wasn’t enough. Genetics. I told him I’d dig up my parents and complain, but except for the exercise it wouldn’t do me much good. 
I’m still not going back to my old diet and hope that the drugs will work anyway. Besides, it’s wonderfully motivating to reject a much longed-for pizza by thinking, if I eat this it will kill me.
Doesn’t matter if it’s literally true or not. Whatever works for you, is good.
