You will cut the tee shirts at the shoulders and the side seams. Then fuse interfacing on the back. I use a light weight Pelon interfacing. I lay the tee shirt face down on a teflon pressing shirt and steam the interfacing to the wrong side of the tee shirt. Then and only then, cut the tee shirt to the size blocks you want. Yes you can add strips of fabric to make them all the same size if you want to. Tee shirt quilts are a good time to use your imagination. You can add patches and appliques and pretty much anything you want. I added a picture of the tee shirt quilt I made for my son for graduation. I will be happy to answer questions if you need help. I hope this helps. You can see the scout patches I added. I made this in 4 "strips the length of the quilt and put them together with a sashing. There are strips between the tee shirts for some stability.
