Best of luck! I too jumped in with a pattern many told me a beginning quilter should avoid (a bargello) and I still love it, it's not a perfect way and maybe some would become discouraged, but I didn't.
With equilateral triangles I like to trim the triangles so the "dog ears" are already off before I sew them together. That way you can line them up exactly. But I now cheat and have a cutter that automatically cuts them that way for me too!
