Cisco Routers :: WRVS4400N Connecting To ASA 5540 IPSec L2L?

I have a remote WRVS4400N that has a dynamic outside address that's initiating a connection to a ASA 5540 with a static address.
 
I'm all set on the ASA side.  My questions relate to the 4400N.  It doesn't appear to have a very robust configuration/setup available for L2L tunnels.  For one my encryption is limited to 3DES.
 
But I'm wondering if I'm missing something in the config.  I have to set up L2L tunnels to two other firewalls.  One firewall has 3 discontiguous networks, and the other has 2.  I have 5 tunnels setup, is this the only way?  What I would like to see is 2 tunnels, one for each remote firewall, but then each tunnel would have access to the appropriate networks (like on the ASA side), is there anyway to do this?  Perhaps a command line util for this unit?
 
My other issue relates to the tunnel-groups I have set up on my ASA's, and I would like to use appropriate names...however I can't seem to find a way to enable this to happen on the 4400N side....what I mean is I need a way to create either a "keyword identifier" or a "firewall identifier" on the 4400N and I don't see an appropriate field in the web interface.
