Hi ...there are several sensors that could cater for your environment based on the ammount of traffic you are planning to inspect. As per the location I suggest placing a sensor behind the firewall ( in in-line between the inside interface of your ASA and the LAN ). In that way traffic to/from the LAN will be inspected. Also .. if you have cisco devices such as routers or firewalls at the remote sites ,you could further protect them by using the sensor as device manager .. in other words you can configure the sensor so that in the event of an attack it can push down access-list entries to your remote cisco devices as well.
I suggest to check the sensor portfolio which will provide you with detailed information.
