We use the SSL Expiration monitor is there any way to maipulate it so that we can check the encryption strength for all of our certs ???
No, the cipher strength is not collected by the SSL Certificate Date Expiration Monitor, but this is something you can post as a feature request in the Ideas section of Thwack. In the meantime you can look at some of the other templates created by members of the community that may allow you to add this type of functionality.
