Learning Point: always drain the tranny before attempting to loosen the bolts.
for drilling out the broken bolt,the upper part of the tranny housing where the bolt sits is a closed end, its likely that i would hv to drill through this closed end while attempting to drill out the broken bolt. this shouldnt be a problem, i hope?

You made no mistake by not draining the fluid first other than the mess it would've caused trying to catch the fluid coming out by not draining via the drain plug, the bolts were either seized or over tightened to the point of about to break, or you turned them the wrong direction trying to remove them.
There's no way only 3 or so quarts of the fluid in the pan could weight enough to put undue strain on the bolts to cause them to break.
You don't want to drill the broken bolts any deeper than the length of the bolts or you could cause damage to the transmission, it's possible that you might not cause damage but it's best to err on the side of caution just to be sure, besides being there's no reason to drill them any deeper.
