Blowing the Shofar

Because I am in the “at-risk” population, I will not go to shul for Rosh Hashana. I know how to blow shofar. Should I blow for myself 30 kolot, as is usually done for those who cannot make it to shul, or is it better to do 100? If the latter, should I do 31-60 during Mussaf and the rest later, or all later?

Shofars come in many different sizes and prices, and they can be bought in many different places. If a shofar does need a hechsher, what should that kashrus certificate cover?

How many shofar blasts must we hear on Rosh Hashana?
