had the bolts that the alternator sits on break clean with the block. Need some ideas on how to get them out. Or atleast a temporary fix to get the truck to the house or to a shop.

 

This applies to most any broken bolts.
Center punch(automatic ones are easier) in the middle of the bolt, start with a small drill bit and drill into the bolt slowly increasing the drill bit size(basically dont jump straight to 1/4 inch bit), use a easy out extractor to remove the broken bolt.
Be careful you don't break a drill bit off in the hole, you do not want to have to drill out a broken drill bit.
For options to get it to a shop, call a tow truck.

 

After you do all the things suggested by Scott up to going up to a larger drill bit after drilling through with a small drill bit, I have had some success using a "Left Handed" drill bit. When the bit bites into the broken stud it has a tendency to unscrew the broken piece. Make sure you soak it well so it is free to come out.
