Your triglycerides are still very high which concerns me because it might be due to metabolic syndrome or familial hypertriglyceridemia. Do another 3 months and fully commit to proper diet and exercise. Keep doing this until they go down to ~100. If you have commited to these changes, have a BMI between 19-25, and still have elevated tryglycerides you need to be evaluated by a doctor for some sort syndrome like the ones I mentioned above (if your doctor won't look into it, then get a new one).
As far as carbohydrates and triglycerides go...
Carbohydrates should be limited to 30-50% of total calories and need to be from unrefined grains (oatmeal, brown rice, barley, and beans). The whole wheat, whole grain bread/pasta is more or less bullshit because the grains still get ground up which increases raises their glycemic index above 50 which is bad. Also excess carbohydrate intake is automatically converted to triglycerides by the liver.
For omega-3's/fat, the pills are okay but you need to be eating fish, nuts, and canola oil with fat intake being 20-30% of calories (completely eliminate beef, pork, and anything with soybean/partially rehydrogenated oil/trans fat).
Make sure you at a healthy body weight (21-23 BMI) and eating a balanced diet of good fat (mono and poly), clean protein (egg white, chicken, tofu, salmon), and unrefined carbs in equal ratios (each ~1/3rd of total calories).
Look up Dr. Ornish's spectrum diet book or anything by Jack Lalanne.
