I do like that you have two door closures. You have a lot of options, honestly, however you definitely don't want to interfere with the closer on top. If you are going to install the chain, take your time. Try to line up the chain before drilling any holes in the door. I'd advise possibly installing the one bracket up into the wood door header, then open and close the storm door while holding the storm door end of the bracket at the top of the door to see the best place to install it without interfering with the operation of the closer.
