since you are planning on driving this car 3.5 hours home I would put all new brakes AND hard and soft lines on it all around. Since these things have the old "crash and kill" single-bowl master cylinder you don't want to take any chances -- if a leak occurs ANYWHERE in the system you will have no brakes at all. its easy enough to change everything out, it can be done in a day if you are at all handy with tools which I would assume you are. Cheap insurance for yourself and others on the road especially since you already had a brake blowout and its not even really moving yet. just my $.02.
as far as bleeding the system you crack open all the bleeders on the wheel cylinders a little bit and let it gravity bleed for a little while. then once there is some fluid in the lines, you close up all the bleeders, then get a buddy to sit in the car and pump the pedal up and hold it (don't bother with those "one-man bleeder kits" they never work right). crack the passenger side rear bleeder and let the air out. the pedal will go to the floor when you open up the bleeder to relieve the air. close the bleeder back up and have your buddy pump the pedal again. crack bleeder and let air out. repeat until no more air comes out of that bleeder, only fluid in a solid stream. Then move to driver side rear and do it all over again. Then pass side front, then driver side front. Don't let the master cylinder run out of fluid. Basically you are using the master to pump fluid through the system to push ALL the air out. And you always go from the farthest point in the sytem (pass side rear) and work your way to the nearest (driver side front). Also VERY important to bench bleed a master cylinder before bleeding the system. Detailed instruction on how to do this are here:
