ParametricPlot3D[ With[{z = r Exp[I [Theta]]}, (#/(#.#)) &[ Im[{I z (1 - z^4), z (z^4 + 1), -(2 I/3) (z^6 + 1)}/(z^6 + Sqrt[5] z^3 - 1) + {0, 0, 1/2}]]], {r, 0, 1}, {[Theta], -[Pi], [Pi]}, Mesh -> {30, 100}, PlotStyle -> {Thick, Yellow}, Boxed -> False, Axes -> None] | |

"that it must range over the closed unit disc" - that should have tipped you off to use polar coordinates. As I don't have Mathematica on hand, try this: ParametricPlot3D[With[{z = r Exp[I θ]}, (#/(#.#)) &[Re[{I z (1 - z^4), z (z^4 + 1), -(2 I/3) (z^6 + 1)}/(z^6 + Sqrt[5] z^3 - 1) + {0, 0, 1/2}]]], {r, 0, 9/10}, {θ, -π, π}, PlotPoints -> {20, 30}]

Your first problem is that vI is a different variable name; you need v I with a space in between.
