Two questions
GND CON Uses 2 frequencies
121.8 (180-359) (east)
121.9 (360-179) (west)
Are these directions based on the location of the tower?

Being a Instrument pilot I know what to do but a friend asked about VFR departures
I know if I want FF I need to call  CLNC BUT for a simple VFR departure would I call CLNC or just GND for taxi instructions?

    Yep, the ground frequencies are based on tower location.

    At a Class B primary, you would call CD for a VFR departure. The hint is that VFR operations in Class B, even something as obvious as takeoff, require a clearance, so you call “Clearance Delivery” to get route, altitude, squawk – pretty much the same CRAFT you get IFR but without the destination or full route detail beyond exiting the Class B.

    Although a “clearance” isn’t required this is also true at most Class C primaries, where they give specific departure instructions which include heading, altitude and squawk code (the RAFT in CRAFT). It’s mostly about division of workload. CD, GND, and TWR (ATIS too) are all tower positions. The busier the airport, the more likely they will be separated.

    This is not request for flight following dependent. It’s just based on the separation services provided within the airspace and the division of tower workload.

    I would agree with the above. You can have CD, GND and Tower all operated by the same person at some airports and at busier airports they are three different people. However each of them serves a different purpose. I always call CD at controlled airports out of habit. If they dont answer or tell me to use GND< I switch.
