Default Do I need a water hardness kit and does the API one work?

It looks like this set is the most common

http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER

but I see some reviews saying the GH test doesn't actually work. Is this true? Also, is it important to test water hardness? Should I do it regularly?

And while I'm here...my water's PH is about 8.3. Should I switch to a bottled water with a lower PH?

Thanks
