Perfect. SEIWA and YEC are good brands in new stuff.
You can replace distributor rotor also, it costs 150-200 and brand is YEC and it takes 1 minute to install. These are commonly wear and tear parts.
In this way, most common wear and tear ignition related items will be new.
Missing is mostly spark plugs, plug wires, valve clearance (tuning) and distributor related issue. Ignition coil rarely fails or stops working.
Install a relay on ignition coil. Overall such stuff will bring improvement in fuel efficiency, responsiveness and should resolve your missing issue.
