If there’s a long line, it’s best to enter the line while filling out the form. By the time you’ve finished, you’ll have moved along quite a ways. If the line is short, or if there is no line, fill out the form at the table so you don’t inconvenience the people around you by holding up the line.
The post office accepts cash, credit and debit cards, and checks (with appropriate ID). The employee should provide you with a receipt of transaction, but if they forget, don’t be too shy to ask for it — it’s the whole reason you’re paying for this service!
