I would get the 55" height. You can then position them evenly from top and bottom. Because they are vinyl (the ones that I got were) I would not recommend cutting them.
Yes. The vinyl shutters that I bought came with hardware. They included 12 plastic screws per set. Installation was a breeze. Per the instructions, I drilled a 1/4" hole in the top and bottom of the shutter faces. The plastic mounting screws are about 3" long. You just use a hammer to 'gently' tap them into the 1/4" hole. My shutters look great!
