ScatterPlot questions

I have two questions:
First: I have created several files of 3D scatterplots from lists
imported from text files.  It looks like this:

<< Graphics`Graphics3D`
SetDirectory["c:\Documents and Settings\chris\My Documents\mathxyeke"]
Directory[]
data = ReadList["33.txt", Number, RecordLists -> True];
ScatterPlot3D[data, PlotRange -> {0, 2}, BoxRatios -> {1, 1, 1.5}, 
  ViewPoint -> {1, .1, -.1}, Boxed -> False, 
  AxesEdge -> {{1, -1}, {1, -1}, {-1, 1}}]

I would like to create a surface plot with this data as well, I found
some discussion in the archives, but could not find any answers on how to 
do this.  ListSurfacePlot does not seem to work, I believe that is
because the points are not uniformly spaced in the x-y plane.  Anyhelp on 
how to do this would be great.

Second:  I have taken these plots and put them in a single program by
copy/paste so that Mathematica can animate them.  I am having a hard time 
exporting these graphics as a animation into a .gif file.  The problem is 
that i cannot define the cells as a "graphic" expression that Mathematica 
will convert.  I gat create .gifs of individual images from the original
files, but cannot create the .gif for the animation.  Can someone give me 
a few pointer?
