Updated instructions for after you've downloaded the script:

-- Unzip the script to somewhere you can find it easily in Blender.
-- Open Blender (getting rid of the default cube and that)
-- File -> Import -> Wavefront (obj) ... navigate to your Vicky, select her OBJ (not her MTL), then chose the following Import settings:
---- Untick Smooth Groups and untick Lines and everything in 'Split By'
---- Tick 'Keep Vert Order' and tick 'Poly Groups'
-- Import OBJ
-- Click on the figure in the scene, press [S] (for scale), and type 10
-- Select Scripting from the Scene Selector (next to 'Help' up the top) - usually says 'Default' by default   
-- In the Text Editor section, select Open and navigate to the code file (called 'FullV4028.py')
-- Scroll down to line 258 (might need to enable line numbering, furthest icon of the three to the left of 'Run Script') and change:
---- path:                             path to your texture files: the images to paint on V4
---- figurObj:                        name of your Vickie - whatever she's called in Outliner
---- clrLimbs / bmpLimbs etc: the names of your V4 texture (colour) and bump files for the face, torso and limbs
-- Run the script
