ok this is what I have, basically have a couple remotes sites that are still using Sonicwall to terminate a P2P fiber connection.  I have some Cisco 871's in hand that I want to replace those sonicwalls with.  The main Site still uses A sonicwall to terminate the fiber and internet filtering.  So basically its setup like this on the sonicwalls at the remote site currently

LAN ip 192.168.5.1
WAN ip 192.168.11.1    Main Site 192.168.11.2 (p2p Fiber)
the main site also terminates all MPLS circuits so we have additional subnets behind the main site sonic wall  192.168.6.0 192.168.3.0 192.168.8.0 192.168.2.0 192.168.10.0.  right now i create address objects in the sonicwall for each subnet, and then route to those subnets through the Main site P2P link (192.168.11.2)  Can the Cisco work with the sonicwall in this way?

From your description it sounds like the sonicwalls are simply routing traffic, this would be a little more complicated if they are doing nat / firewalling, but the 871 can do both.

The 871 should be able to do what you are asking.  You would create the LAN and WAN ip addresses, then add static routes for each of the remote networks (via the main site ip address.

would i need to create an ACL for each remote subnet?

that would depend on the security setup you need.  For simply routing the traffic, no, you would not need an acl, just a static route.  If you want to control / limit traffic, or you will be doing nat / firewalling, then you will need to create acls, create nat statements, etc.
