The wheel is correct (same part number as mine). The tire is the right size. Note that someone will have to mount it to the wheel. Cost should be ~$15-20. The jack part number you linked to is only the jack. The wrench and extension pin and plastic holders are not included! You are better off going to a scrap yard or used parts dealership to buy an old set...
You'd have to do some searching but GM has a foam ring available that goes under the tire.
Found a '14 Impala with 125/70/17 spare in mint condition at local yard yesterday, $18 with $2 yard entry fee. Will have to keep hunting for a complete jack kit.
Apparently the jack kits are a hot commodity (b/c scrappers?) - I only found one jack among about 150-200 GM cars and it was rusting in a pool of trunk water. Plenty of 16" spares to be had, mine was the only 17" there. Also noticed many cargo nets intact and in good shape, about $4...these are the GM trunk cargo nets so they're about 4'L x 1'H or so. I'd imagine you could find one pretty easily at your local yard if that is of interest.
Apparently this yard gets frequent gravel storms; several trunks had copious gravel/mud deposits. Also of note - an '08 Saturn Aura has much much nicer leather seats than our '18 TourX. SMH yet again at GM's bean counters. But it was cool looking at old cars, many of them in very good shape.
