HOW TO DECIPHER THIS INTERESTING ENTRANCE WALL COAT OF ARMS

My friend lives in this great condo on Montagne, and the lobby had this stone on the wall. Unfortunately I am a poor symbologist, but this combination of skull and caduceus was too intriguing not to attempt to understand. After trolling the internet, here are a few (plagiarized) ideas. There are only four certain symbols I could identify: the fasces, the caduceus, the  (bay) laurel wreath (a tradition begun in the University of Padua), and the oak branches with acorns.

Here are a few links to symbols used on Coat of Arms:
Fleur de Lis , Family Tree and Crests, The Red Thread

From top to bottom, left to right:
Rising star (5 points ?3rd son, excellence, good luck)
Skull - Mortality
?
Sun - energy, success, power
Bundle of rods around an axe: Fasces, an Etruscan symbol for strength through unity
Eye and Ear - Sight and Hearing
Alpha Omicron- The only lead I found on this is a Concordia Fraternity called The Omicron Brotherhood, but I haven't found a connection with Alpha. The idea I had of Alpha and Omega still lingers. Although not the greek symbol, the circle  could represent eternity and fidelity.
Lips - Speech
Oil lamp - light, life, spirituality, learning, wisdom
Right Hand, dorsum
Feather - obedience and serenity
Harp - Represents a well-composed person
of tempered judgment. A bridge to a
mystical contemplation. Music.
Laurels - Peace, Triumph, Victory and Caduceus - medicine, balance/union of opposing forces.
Oak branches with acorns - continuous growth and fertility
