Help with 3D graphics


I am doing a project for school and need to be able to plot a 3D graph that
goes from 0 to 1 in x, y and z directions.  I also need to be able to plot a
set of 3d points on the same graph as the 3d graph.
Here is what i have so far, the problem is that my second graph does not go
from 0 to 1 in the z direction like the first graph.  I think it is a
problem with converting Plot3D to Graphics3D.

Show[
  Graphics3D[{ PointSize[0.05], Point[{0, 0, 0}] } ],
  Graphics3D[{ PointSize[0.05], Point[{0, 0, 1}] } ],
  Graphics3D[{ PointSize[0.05], Point[{0, 1, 0}] } ],
  Graphics3D[{ PointSize[0.05], Point[{0, 1, 1}] } ],
  Graphics3D[
    Plot3D[2x + y, {x, 0, 1}, {y, 0, 1}, PlotRange -> {0, 1},
      ClipFill -> None  ]]

  ]

Would my problem be solved if i used ScatterPlot3D to plot the points.  The
problem i've found with this is that ScatterPlot3D will not work in Show
command.

Thanks
