Yeah, the routing is done according to the routing table.
You can use these command to display the table:
* route
* netstat -r
* ip route
see man pages for more options.

Answer to your question about configuring routes is possitive :)
You can run nm-connection-editor (nm-applet right-click->"Edit 
connections...". Go to "IPv4 settings "tab add click "Routes...", where you 
can specify manual routes.
Also, if you check "Use this connection only for resources on its network", 
the device on which the conection is activated won't get the default route.

As far as D-Bus are concerned, you can get all settings (including routes) 
from a configured connection:
dbus-send  --system --print-reply --
dest='org.freedesktop.NetworkManagerSystemSettings' 
'/org/freedesktop/NetworkManagerSettings/0' 
org.freedesktop.NetworkManagerSettings.Connection.GetSettings

replace 0 with the appropriate number for your connection.

When you have an active connection, IP configuration can be obtained as 
follows:

dbus-send --system --print-reply --dest='org.freedesktop.NetworkManager' 
'/org/freedesktop/NetworkManager' org.freedesktop.NetworkManager.GetDevices

dbus-send --system --print-reply --dest=org.freedesktop.NetworkManager 
/org/freedesktop/NetworkManager/Devices/1 org.freedesktop.DBus.Properties.Get 
string:org.freedesktop.NetworkManager string:Ip4Config

dbus-send --system --print-reply --dest=org.freedesktop.NetworkManager 
/org/freedesktop/NetworkManager/IP4Config/1 org.freedesktop.DBus.Properties.Get 
string:org.freedesktop.NetworkManager string:Routes

again substitute the numbers for your actual values.
