Re: cleat position. Note the widest part of your foot, where there is a knobby bone at the base of the big toe. Put masking tape on the side of each shoe, on the big toe side, in the general area of the widest part of the foot. Draw a vertical line on the tape at the widest part of your foot. The center of the cleats should line up with the lines on the tape.
Re: hot foot. Try different insoles. I personally like the LG insoles, which you heat in your oven and then put in the shoes to mold them to your feet. The insoles that came with my new (Bontrager) shoes had a nice arch support but were too thin under the balls of my feet, which caused pain/pressure on my feet over the cleats.
