Which safety valve should be set to discharge at lower pressure drum safety valve or super heater safety vlave?

The Superheater safety valve must be the lowest set safety valve on any boiler, in order that flow through the superheater is maintained.
If the drum valve were set lower the flow through the superheater would be disrupted on an overpressure.

Why should you never front seat the discharge service valve while a compressor is running?
This will cause the head pressure to climb very high and if something doesn't explode or cut out on a high pressure safety, you and the equipment will be damaged. Hopefully compressor will be one with internal or external overload. To summarize DONT DO IT WHILE COMPRESSOR IS RUNNING.

There should be tripping safety mechanism in wall heater.
Why would a faucet have high water pressure when first turned on and then quickly slow down?
Generally this is caused by pressure being built up from the water getting hot in the hot water heater. By code you should have a hot water heater expansion tank on the cold water inlet of the water heater to absorb the added pressure. If this is your problem, the excessive pressure could possibly burst your water heater. The faucet stem or cartridge or washer may be loose or moving and blocking flow.
