High Lipo (a) and homocysteine. Day?

My father and his family has a history of cardiac diseases, recently for heart palpitations i had consulted doctors and my ecg,echo, blood pressure and HbA1C are normal and i avoid any oily or fried foods like 90% of the time. The blood report showed high Lipo(a) around 84.6 mg/dL and homocysteine at 25.77 and my lipid profile is only little off the chart! My vitamin D3 were extremely low so currently i have been asked to take lumia60k once a week and B12 on daily basis even though my vitamin B12 level were under normal range. I wanted to know should i be taking K2+calcium and magnesium along with D3 ? Would they be beneficial if i take them every day? Also as mentioned earlier that lipo(a) is a genetic marker and nothing much can be done, what other precautions needs to be considered for such markers. I am planning to get second opinion as in the first consultation the doctor didn't prescribe any meds as i am in my early thirties. Any further recommendations would be appreciated
