I can't help you with the 4096, but I should be able to help you out with the rest.
Let's split cut off the d and then split up drwxr-x--- into three groups.
rwx: The first three letters define the permissions given to the OWNER of the file. Read, Write, eXecute.
r-x: The second three letters define the permissions given to the GROUP the file belongs to. Read, no Write, eXecute.
---: The last three letters define the permissions given to everybody else. No Read, no Write, no eXecute.
psaserv is the group the files are assigned and alluded to above, just like root, kyrathaba and apache are the owners of the various files.
