Set the PlotRange-option. This will do what you want:
plotdata=ListPlot[data,PlotStyle->PointSize[0.01],PlotRange->{{0,6},{12,18}}];

Why a bitmap ? Copy it as MetaFile or ExtendedMetaFile.

The ImageSize option ?

A bug in Word ?

Encapsulate PostScript.

There are so many versions in Matheamtica 3.0, here is one with 12 pt
Times Bold Italic:
plotdata=ListPlot[data,PlotStyle->PointSize[0.01],PlotRange->{{0,6},{12,18}},
AxesLabel->{"some x-values","some y-values"},
TextStyle->{
FontFamily->"Times",
FontSize->14,
FontSlant->"Italic",
FontWeight->"Bold"
}
];

Place :
SetOptions[#,
TextStyle->{
FontFamily->"Times",
FontSize->14,
FontSlant->"Italic",
FontWeight->"Bold"}] & /@ {Plot, ListPlot, Graphics,
ParametricPlot}
in your init.m file and be sure that it tis the right one.

Look in the nice book "Mathematica 3.0 Standard Add-on Packages" that
comes with Your Mathematica copy.

You will be surprised it is in
Main Menu | Help | Help ... | Add-ons | Standard Packages | Statistics

What is the "bestfit" command ? Fit[] can only used in linear models.

Mathematica is a Computer Algebra so You can use any mathematical
combination of the special functions implemented in Mathematica.

Hope that helps
