Connect to parent company

Hello
We have just been taken over by another company based approx 200 miles away and need to connect the 2 sites.  Both sites have approx 50 users and there are also approx 80 remote users.  Applications will be shared between the 2 sites and we will adopt a common email address.

My questions are:
1.) What method do you recommend to connect the two sites
2.) What should I put at the 'ends' at each site
3a.) Both sites have their own exchange server.  Should the satellite office just use the one at the head office and collect emails via the VPN or should we keep both servers and connect using RPC.
3b.) If the answer to 3a.) is use RPC then can you provide brief explanation of how this works.
4.) Both sites have their own domain controller.  Should we keep it this way?
5.)  Baring in mind the above,  how should the IP addressing schemes of both sites relate to one another?

Many thanks.

1.  Site-to-Site VPN, We use Cisco PIX 506e here
2.  Cisco PIX
3. Not sure whether both sites should have their own Exchange server, but I can tell you this, that we have only 1 Exchange server, and its in the U.S., the rest of our company in India via Site-to-Site VPN get all their email from here
4.  Each site should DEFINITELY have their own Domain Controller, becaue if one day the Site-to-Site connection is down, users at either office will still be able to Login to the Domain, granted that you have to configure each Domain Controller as a Global Catalog Server, you may want to have more than one domain controller at the main Site for redundancy purposes
5.  Well, based on the above, you can do something simple like 192.168.1.0/24 for one Site and then 192.168.2.0/255.255.255.0 for the other site, and since the PIX will be acting as the Gateway, traffice will route between the offices just fine, it also allows you to distinguish traffic (if need be), when creating the rules list in the PIX

Keep in mind, that each company should have ample Speed for their connection to the Internet, because the Site-to-Site will have to be fast enough to support the Applications that will be hosted.

1) Same as above
2) same as above
3) If there is a large amount of mail traffic you should mantain at least one (2 would be better) Exchange servers at each site.
4)Same as above
5) Same as above

P.S. For number 1 if you expect large data flow you may want to go with a more robust VPN product like the CISCO 3000 series concentrator as it can handle more thrughput for encryption and is expandable.
