...I know you said you are strapped for cash, but the way I would work on figuring this out would be to start with a pair of wheels that are true and dished correctly in the rear, so they run true in the center of the fork and rear dropouts of a bike you're certain of. Put them in your new frame, and eyeball what they look like, in terms of running centered and vertical. Then I would go from there.

It's usually not a big job to cold bend a frame with some minor misalignments, but unless you've done it before, you should get someone who has and knows more of less what he is doing to kind of show you. Otherwise, don't just start randomly bending something, from assumptions made by watching Youtube. There's a relatively logical procedure to follow.

I wouldn't presume this bicycle is a write off this early in the process. And you can learn a lot from it.
