Mike,

The distributor will probably need to be replaced to solve the ignition problem.  The batttery thing is going to be a pain.  If the cables were backwards you probably have some smoked electrical components.  First, check and replace all fuses blown and that includes those at the positive batery cable.  Now, that means the fuse links too.  The polarity reversal could also cause the radio to blow internally and the computer that runs the engine.  You might get lucky and check the fuse links and fuses and then change the distributor and get a fully charged battery and see how things go.  Also, once you get it started you might discover that the diodes in the alternator are blown too.  It just depends on how long the cables were hooked up wrong.
