Those flippers will work for awhile but there are much better options available. As mentioned you can shoot off the shelf too but you'll need to put something on it first.
Instead of experimenting to find the right arrow I'd recommend going to your local bow shop and have them show you what arrows you need. Then they can build your arrows however you want them. Doing it yourself requires a bit of experience and fair bit of knowledge plus the proper equipment. The bow shop can show you all the options for arrow type (aluminum, wood, carbon), fletching (plastic vs feather, length, helical vs straight), proper arrow length (need to measure your draw length), choosing your tip weights as well the right spine.
