Answer 1

You can select both of those elements by their name attribute.

//input[@name='firstName']

and

//input[@name='lastName']

If you are using java (you don't mention your language) and you have a WebDriver defined as "driver" you could use either:

WebElement firstName = driver.findElement(By.xpath("//input[@name='firstName']"));

or alternatively you could look it up specifically by name:

WebElement firstName = driver.findElement(By.name("firstName"));
