Technically hardy to 40 F, best kept above that temperature. Ginger doesn't particularly like cold tootsies, although it's fairly hardy as members of its family go.
What you're looking for in a starter chunk is that it be very plump and firm with no wrinkles, no squishy spots, and no mold on the break surfaces (rarely if ever do entire rhizomes make it to market in the US). It should have a pleasant and mild ginger scent when sniffed - if it's at all musty, it's been artificially plumped and should be avoided.
It will sprout anywhere from immediately to a month, no deeper than 1" and preferably about 3/4" under in frank soil with very fast drainage (cactus soil 50-50 with potting is a great blend for any ginger or relative). Sprouting range seems to be 60-75 degrees, and after it's up as long as you keep it watered and in good light it will keep growing.
Up pot after about a year (divide your rhizomes) to keep it happy - it will easily and effortlessly crowd itself out of the pot you've got it in, and division is key (as well as giving you a modest harvest of tasty ginger, of course
