Your pump has 3/8 inch output an dinput. go to lowes or Home depot, and find a 3/8 inch male to 1/4 inch female adapter, then get one from 1/4 inch male to 1/8(internal diameter!) inch barbed. They do not carry a 3/8 inch male to 1/8 inch barbed adapter.
It's confusing, I ended up buying a 1/4 barbed one that wouldn't fit my hose. Make sure you remember that the 1/4 inch hose is measured by external diameter, while the barbed adapters(the ones that fit in the hose) are measured by the INTERNAL diameter of the hose - condusing.
Metal will work, just DO NOT overtighten it. Wrap EVERY thread in teflon plumbers tape - they carry that, it's cheap.
For now, just ream out a hole in the lid of the bucket, and drop in the hose. Worry about the bulkhead when you have time(and instructions)
Run the hose up to the first nozzle, then run it off a tee(if your'e using elbows) or just stick in place, then go to the next.
Secure all the hose joints - THEY WILL SLIP - it really ticks off my wife when water is hosed at high pressure up against the bedroom door in the middle of the night from across the hall...
Where you do not have extra screw clamps, just use small plastic zip ties, and tighten with a pair of pliers - they work.
