Domain Controllers and DNS for office location and DR site connected by MPLS network

I currently have 2 office locations and a DR site that are all connected via an MPLS network.  Each location is on its on subnet as follows:

DR site 192.168.3.xxx
Main Office 192.168.100.xxx
Fleet Office 192.168.3.xxx

I am trying to figure out how to setup the network a the new combined location's far as DC's and DNS as well as DHCP.  Should I just combine them into the same subnet 192.168.200.xxx making sure that I have allocated enough IPS as needed? The DR site will stay on the same subnet its on now 192.168.3.xxx
How many DC's do I really need?  I have two at the DR site and 2 at the new combined location currently.  Any suggestions would be appreciated!

I would not suggest combining subnets across sites. Use at least /24 for each site. Ideally you want one dc at each physical location to minimize traffic over the Mpls. Active directory sites and services is what you setup to tell each subnet which site it belongs in and therefore which dc to use and how the DCs replicate

Okay, thanks for you input. What about DNS?  The DR site is a .local domain and the new combined office is xxx.com  The xxx.com domain is active directory-integrated primary and the xxx.local domain is secondary, both are forward lookup zones in DNS.  All Dc's have both zones loaded on them as such, this is the way the DNS was setup prior to my being here, but I am having some slight DNS issues with server name resolution.  Is this a preferred way to have the DNS setup or should it be done differently?  Thanks

Normally I would just put each zone on its servers and use a conditional forwarder, but I'm not sure if that works with .local. Personally I always use a subdomain of a registered real domain like corp.domain.com
Maybe someone else will have experience with .local and conditional forwarders.
