Why the temperature swings
A valve that is not pressure-balanced sees the cold side drop when something else draws cold water, and the mix at the head follows it. That is the fault anti-scald valves were introduced to remove.
Cartridge or valve body
A shower that drips is usually the cartridge, which is a part. A shower that will not hold a temperature when a tap runs elsewhere is usually the valve, which is behind the wall.

Checking a plumber in Missouri
Missouri has no state plumbing board. Section 341.010 of the Revised Statutes requires a certificate for plumbers working in cities or towns of fifteen thousand or more inhabitants, and the chapter elsewhere recognizes licenses issued by any county or city operating under plumbing rules, so the office that issued one is a local office. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.
