So we already have <ourcompany>.onmicrosoft.com and <ourcompany>.com registered with Office 365 but we've just created a new web site and a new domain name.

We want to add <newdomain>.com to Office 365 but in such a way it does not impact mail flow. Then, once the new domain is ready to go live we can switch the default domain in 365 from <ourcompany>.com to the new one.

Obviously we will want to direct email sent to the old addresses to the 365 mailboxes belonging to our staff.

Is it literally a question of clicking 'Add domain'? I'm just concerned where it reads 'Would you like to change your Office 365 email address now?'
 
It does not add the domain to any mailboxes by default. You will only receive mail on the new domain if you set it as an SMTP address on an individual account.
