Okay to get right to the point. I have this old mtb that I just got and the back wheel had some major wobbles to it when I got it. I used the tire and frame as a guide and got the *big* wobbles out. Then last night I was going to ride it for my after dinner short ride and I had a flat tire, I took the wheel off the bike, took the tire and tube off the rim and patched and re-assembled. Now when I spin the wheel my tire rubs on my chainstays. I have tried changing the angle of the wheel slightly and it seems that if I do the tire rubs on the other side. Now I know this is probably caused by the tire not being mounted back on the rim in exactly the same place. My question should I try to *re-true* the back wheel using my tire / frame method. Or is there some other simpler solution to my problem?

It's your "tire/frame method" that hosed up your damn wheel in the first place. Or second place assuming it was imperfect when you started.
True the rim to frame, not the tire. The tire's made of rubber and air and flexes and shifts, truing to that's like nailing jello to a tree.
In fact, you're at the point where you'll need to get the tire off of there to salvage this thing. The beer and wheel truing post explains this all pretty darned well. I'll recommend his advice.
