tape the rings on and load the rod to see if everything looks good if it does have a few wangs to see if all is well before you put them on permanently
as for putting the first ring on backwards sure why not it defo wont affect the action and will give any coils of line less to get tangled in ,are you using a fixed reel seat? if so i supose you could tape that on aswell till you got it where you like it too
