I think the one's I've used for my wife's paintings were the more expensive "heavy duty" ones from that brand. But yeah, something like those is what you use.
Other sites to check are Dick Blick, Utrecht, Jerry's Art-O-Rama and Art Supply Warehouse. Usually at least one of them is having a sale on some type of supply so you might be able to get a good deal.
Lots of videos on youtube that say exactly what to do. The main thing is to do it evenly so it doesn't get twisted.
The other option to consider is gluing the canvas onto a panel such as Masonite hardboard.
