Default New guy with serious electrical problem! (ES 300)

Hello fellow Lexus enthusiasts!

I come to you with a pretty ugly electrical problem....

To make a long story short, I believe that a jump-pack or jumper cables were hooked up backwards with
the car's battery completely flat. After that it would crank but not start.

A bit more investigation revealed that about 3 fuses were blown - two up front, and another in the
cabin. Upon replacement the car will now start and run, but is only running on the battery charge. IE:
the alternator is not charging. Additionally many accesories will not function (gauges, radio, power
windows, etc), and the transmission selector will not unlock from park.

Could the alternator's regulator circuitry have fried and caused all these other devices to not
function? Should I expect replacement of the alternator to fix everything else, or does this indicate
something more sinister is in play?

Any direction or sugestions you guys have would be appreciated....

What say ye?

Thanks,
Rick
