I have this setup, and it works good.
The site-to-site VPN is done at the routers, IPv4 and IPv6 work spot on. You need to get the connectivity working before you can get started on anything else. I have one user account setup on each router for remote access when away, like you mentioned.
I've also got folder redirection working with DFS and replication so that wherever anyone logs on, everything is still there and the same. Works well with films etc as the servers run TVersity for media streaming. I download the films, and the media libraries are kept sync'd up over VPN. It's very handy.
It was a bit of a pain sorting out the site-to-site VPN, but I was learning at the same time with new hardware and software. Make it up as you go along kind of thing. I use mikrotik routers at each end over cable internet (virgin media).
I am half asleep at the moment, but please reply and I will offer any help needed to get your setup going.
