Given your thoughts on how you want to proceed, I would recommend that your attachment points be fairly high on the wall. The closer you are to the top plate the less deflection of the wall stud will occur and the less likely you will be to cause cracking in your wallboard or plaster.
I don't think you'll need any sort of bracket for your application (using load buckles) the screws should all be loaded mostly in tension (stretching) which should be fine. Try to arrange your fasteners so they are into the meat of the stud and not just catching the edge. Angle them if necessary. Remember that your fasteners need to pass through a thickness of wallboard or plaster to get to the wall stud so allow adequate length. I like to pre-drill for larger fasteners to avoid splitting the wood and sometimes I pass the threads of the fastener across some parafin (candle wax) to lube them up so they drive easier.
