OK, you can call your Samba AD domain anything you want, but you 
shouldn't use just your registered domain name.

 From your example 'thisismycompany.com', 'internal.thisismycompany.com' 
or 'myco.thisismycompany.com', would be ok, but 'thisismycompany.com' 
wouldn't, you can then call your workgroup anything you like i.e 
'INTERNAL' or 'MYCO' etc

As for username, it would generally be in the form of 
WORKGROUP\username, but on a member server, winbind can be setup so you 
would only require the username.

Don't do this, set up bind to use the DLZ zones in AD, I take it that 
you realise you need to run bind on the samba4 AD server and forward 
everything that is outside the AD domain to another DNS server.
