I would advise to work with a list of vectors and make loops as you suggested. You can write a function grid(v1,v2) (plus fancy parameters) and apply it to grid(A*v1,A*v2).

About Sage, i would start by:
sage: V = VectorSpace(QQ,2)
sage: v1, v2 = V.basis()
So that my vectors live in a safe place. Then, after defining a grid() function that returns a Graphics() object built as a sum of lines(), i would write:
sage: grid(v1, v2, color='blue') + grid(M*v1, M*v2, color='red')

I would advise to work with a list of vectors and make loops as you suggested. suggested, this is a smart way. You can write a function (plus fancy parameters) and apply it to grid(v1,v2)grid(v1, v2) for some matrix grid(A*v1,A*v2)grid(M*v1, M*v2)M.
About Sage, i would start by:
sage: M = matrix(QQ, [[1,1],[1,0]])
sage: V = VectorSpace(QQ,2)
VectorSpace(QQ, 2)
sage: v1, v2 = V.basis()

Do not hesitate to ask for details about the grid() function if needed.
