Thanks for the help. My statement above that the ASA 5505 doesn't appear to use access-list was poorly worded. I've tried various combinations of access lists without success. It appears the ASA ignores them. From my limited understanding adding the entries you suggest should allow the traffice from the outside interface to the inside and because it is a tcp connection the inside interface should allow the traffic back to the source. I'm sure it is something I'm doing wrong, but after putting the ACL in and assigning it to the outside interface it still doesn't allow SSH from the outside host to the inside hosts.
I'm not really familiar with using object groups and haven't tried that yet, but will start looking at it.
Below is a configuration with the changes you suggest. I'm not able to SSH to the hosts on the inside.
