Q2 – Can this system be linked into a standard garden hose fitting?

Yes. The faucet connector is the same size and thread as a regular garden hose (3/4″). It is recommended for your convenience to use a Y-splitter at the garden faucet so you can also still connect your garden hose.  With a four-way splitter you can have one for the Plant Booster system (which you leave on always), one for your garden sprinkler system, one for a hose pipe, and one spare.
