How do I know the valve needs replacing?

Tell-tale signs: the handle turns but water doesn't fully shut off; the handle is stiff and needs two hands; drips under the handle (stem seal); visible corrosion on the body. If any one is present — plan a replacement within a month.

Who shuts off the riser when the apartment valve is being replaced?

Usually the plumber arranges with the Vaad Bayit or finds the valve in the basement/roof. In large complexes a request to the management company may be needed a day or two in advance. In smaller buildings — the plumber goes and shuts it down (neighbors on the floor are notified). Plan the replacement for a weekday morning.

Can I install one large valve instead of two (cold + hot) at the inlet?

No — these are separate lines, they must be shut off independently. A single valve for two lines is physically impossible (they're not connected before the boiler). Two separate valves are standard.

How long does a quality ball valve last?

A European brand (Bugatti, Tiemme) — 20–30 years if it's exercised 1–2 times a year and the water isn't aggressive. Israeli Valogin — 15–20 years. Chinese no-name — 3–7 years. Price difference 30 vs 150 ILS, lifespan difference 3–5×.
