Answer 2

Regarding Windows install above. .img files are .iso files when decompressed. After unzipping either of the images above using 7zip just rename the file with a .iso extension and select the unlisted option from the Universal USB installer. The centOS options is for regular centOS image, not the one above.

Answer 3

After getting the appropriate image, follow the instructions found on https://www.raspberrypi.org/documentation/installation/installing-images/.

Currently Etcher is recommended as "the easiest option for most users" for an SD writing tool. It has a graphical user interface and supports multiple image types (*.img, *.iso, *.zip, etc).
