I would like to know if there is any Byzantine Catholic parish in or around Las Cruces.
Can't answer that one.
There are some good areas for 55 age plus people around the city?
Las Cruces is rated highly as a retirement destination for many people. There is no specific area but there are many options for "retirement homes" or senior's-only developments.
How is Santa Tereza or Sonoma?
Santa Teresa is not part of the Las Cruces metro area. It is a community abutting El Paso, but located on the NM side of the state line. Sonoma Ranch is a large area of development within the Las Cruces city limits.
In general, Las Cruces is divided into two zones:
The Rio Grande/Mesilla Valley which is formerly flat irrigated farmlands. Lots of greenery and good growing conditions, assuming adequate water availability.
The eastern foothills of the Organ Mtns, which is where most of the latter day development has occurred and is still developing apace. Sonoma ranch is in this area. Water is a greater issue and gardening is minimal with Xeriscaping the dominant theme of most residences. Think dry desert land.
Google aerial and street views are your friend when researching unfamiliar terrain.
