I would wait to do the alignment until you do the ball joints and coil spacer, unless, like you said, you like to pay for two alignments. You can adjust the toe yourself in your driveway, to at least make it a little more driveable until then.
I'm sure you know what toe is, but just in case:
Looking from the top of the vehicle, like a top view. You want the tires to be | | However, incorrect toe may cause them to be / \ (toe in) or \ / (toe out)
A quick, but not a precise way, to do it, is to use a tape measure the distance between the fronts of the tires and the rear of the tires. For example, find a place of the trade on the front passenger tire and measure it to the same place of the tread on the front of the driver side tire. Then measure the same place of tread on the back of the passenger tire and measure it to the same place of trade on the back of the driver tire. I hope this makes sense. You're going to want them to be within ~1/8" - 1/4" of each other.
This will at least make it a little more driveable until you get your ball joints and spacers and alignment done.
