Another thing for more help go to
Youtube and search,
for "Blender tutorials" my brother taught himself to model there i recommend it.
Another thing, the easiest add-on to make is decal's and faces because they don't require scripting
or modeling, I recommend trying that first.
Another thing again, There are three modeling programs that i know of.....
Blender - free
Milkshape - 20 dollars i think
And torque constructor also free.
