tampam4,
Your shins hurt on either side b/c you're heel striking and wearing a shoe with an elevated heel. This shortens your achilles and puts stress forward on the foot. As with most, your probably over striding as well. No shoe will fix that, it will mask it temporarily. Eventually you'll get stress fractures.
Learn to be a mid-foot striker and take short quick steps. If you can adapt to a minimalist shoe it will align your spine, lengthen your achilles, and weigh less than what you have now. I average about 60-70 miles per week in NB 100's on all kinds of surfaces.
As for the The Brooks Beast, it has long been the favorite of big guys. How big are you? A shoe like that weighs a lot, and your lower leg muscles, which are already taxed b/c of the heel striking will now have to pick up a heavier shoe 2000 times per mile which won't help your cause.
Be wary of running shoe stores and their gimmicks to find out what type of foot you have. Your best bet is to get with an ultra runner and let him watch you run. We look at ourselves and others running way more than anyone else.
If you have to go with a "cushioned" shoe, try to get one with a flat sole so your foot works like designed.
