The bobbin change should be no problem in that set up. There is an access door on the top of the bed next to the needle plate and another access door in the front of the machine. The whole front opens! With the machine facing you as it would be, I can't imagine why you would have trouble. The mistake people make inserting the bobbin is because they may have been told to hold the little latch open on the bobbin case. There is no need to do this. Insert the bobbin in the case, threaded correctly, of course, and line up the little nub beside the latch with the cut out on the hook race and push it in until it snaps into place. Once you see the bobbin case you'll understand.
Another problem arises if they don't have the needle at its highest position - it is the same with any machine, but the Brother 1500 seems to get a bad rap for some reason.
