I'm establishing a hub and spoke setup with ASA 5505's filtering traffic between 5 sites, with a central hub. I've utilized this setup previously, but for some reason we are running into issues with new ASA's (version 8.2.5). I'm working with just 2 sites right now, basically peer to peer, and cannot ping the inside IP's from either end, and cannot ping the inside gateway unless through the console.
Here's what I've got (I took out the first two octets of the outside address, assume they are the same throughout):

You can't ping because you don't allow ping on ASA, try adding icmp permit any any outside for testing purpose. Your VPN config looks ok to me. Try enabling the debug crypto isakmp and debug crypto ipsec, to see why it's not establishing the tunnel. After you enable the debug, generate a packet that matches your crypto ACL and post the output here.

There is no need to specifically define ICMP on the ACL's anymore
policy-map global_policy
class inspection_default
inspect icmp.
That aside I would suggest you verify that the VPN tunnel is up.
sh isakmp sa
sh ipsec sa
when sanitizing you config remove the route outside 0.0.0.0 0.0.0.0 55.11.214.129 1 <--
