I'm convinced starch (or Best Press) is awesome, as is very accurate cutting, pressing, and sewing. I bought an 1/4" edge foot for my Bernina last winter and it's made a huge, huge difference for me.
As for ripping out seams, I do rip and re-do if a seam is more than a little off. I don't think I've had to do it more than twice, and that's really rare. I do use pins if I need to, and I sew very slowly, using my awl to feed the fabric through carefully.
I have been known to toss a block and make a new one from scratch, but haven't had to do that in a while. Be patient with yourself, relax, and enjoy the process. As they say, Rome wasn't build in a day!
