Form 3520 from parent

Each of my parent (both are NRA) give me gift of $50k so since they are related the total reaches $100k. 

So my first question will be that do I file one 3520 with both transactions listed or two separate 3520 and if have to be 2 forms can I mail them together in one envelope ?

Then both transactions are wire transfer of cash from foreign person , so I only need to fill part IV right ?

Although I will be filing tax return jointly with my wife , the 3520 form is not jointly as both transactions were from my parent is that correct ? 

Do I need to attach any notice or receipt from bank?

 

Thanks
