You can either send it to me and I'll calibrate it for you at no charge, or you can try to do it with a multimeter, but I've never seen anyone do it successfully with just a meter, personally.
To try it with a multimeter, you'll need to download a file called "max.wav". You can find it here. You play this file with windows media player and adjust each channel so that when the file is playing they provide 5v and when it isn't playing they provide 0v. You will adjust the gain and offset pots on the correction amp to accomplish this.

i decided that im just going to leave it on a metal sheet until i get a enclosure for it. the only concerns i have now is how i connect everything all together? i know ive asked this a lot but im just not understanding it at all. lol if u can label the pics that u have uploaded for your sound card dac tutorial, u think u can mark what wires i need to connect to where? that would be very helpful

I can try later if I have time.. Once you have the parts, everything is very clearly labeled on them.. it's not hard to figure out as you go. Also, this link will help you out:

You're not actually modding the soundcard, no.. you're merely modding it usage. And yes, you would cut the connectors off the ends of the galvo wires and connect them (the positive and negative wires) directly to the DAC. There are three wires coming off your amps +, -, and ground. You can ignore the ground wire.

That's correct. You'll also need to connect the modulation wire that comes out of your laser to the DAC as well, but there are also pins for this in that same row. I believe Ch. 4 on the DAC is for green-only systems. So in total, you'll be using Ch. 1 and 2 (first four pins in the output row that I described previously) for the X,Y galvos and Ch. 4 (pins 7 and 8 in the output row) for laser modulation..

You'll tune it before you solder the wires on to the pins (I use a connector myself but soldering will do..). You just put the multimeter on the pins where the galvos will go. I'd go ahead and tune up the other channels when you do it since it's very easy and you will then be able to continue using it when you get a proper laser.
