Answer
Your dog sounds very anxious, as though your leaving is very stressful for him.  Dogs will often try to make themselves feel better by chewing, or by urine marking.  This often happens when dogs are not socialized well as very young puppies (age 8-12 weeks) and become overly dependent upon their human family and distrustful of novel situations.  His aggression toward strangers is very likely a response to his fear and anxiety.  My advice would be to find a behaviorist with whom you could work to gradually diminish the dog's fearful responses.  If you don't have access to that, there are two very good, yet inexpensive, books that might prove very useful to you.  They are both by Patricia McConnell, and available at Amazon:
"Way to Go - How to House Train a Dog of Any Age"
"I'll Be Home Soon - How to Prevent and Treat Separation Anxiety"
