berniebenz,
Hi pressure side starts from superheated gas and ends up subcooled liquid refrigerant. After this subcooled liquid refrigerant will be pushed into metering device, wich has very small hole in it (compare to liquid line). Just keep counter flow to water and forget about other things. liquid line will be full of liquid if you have enough charge.

Regular flare is good enough but brazing is still much better. Just braze it and forget it. Copper is super friendly material and you can stretch it bend it.... here look how I build distributor just from few pieces of copper tubing

If you have friend HVAC tech I hope he is refrigeration tech. Refrigeration systems are tricky and unless you want to learn a new trade just ask your friend to help you.... Also you need a ton of tools to do the job right....
