What is the extension of your studied area?, are the data homogenously distributed?
According to the scale of the zone and the distribution of the data, the number of data has importance for the resulting resolution of the grid. It is possible to use several tools to grid bathymetry data: GMT, Surfer, matlab, and many others.....

yes you can certainly generate bathymetric map, any 3D plotting software will be helpful. Andrei is right SURFER, can be good for such plottings, or you can use any GIS to generate a 3D surface.
Yes you can create a DEM of the bathymetry of your study area. The quality of the DEM will depend of the extent of area covered and the sampling resolution. You can use GMT (Generic Mapping Tool software) for that. GMT is free and very good for mapping.
ArcGIS has quite good interpolation tools as well. If you have a license, I suggest to apply kriging and then do some experimenting with the semivariograms. http://resources.arcgis.com/en/help/main/10.1/index.html#/na/009z00000076000000/
If you want, you can use tools like OpenJump GIS , QGIS or SAGA GIS. The last one works very well in the creation of DEM and you have some methods of imterpolation, kriging, IDW, etc.

The previous answer provided you with the tools you can use. However, I should mention that 2000 points is not a lot for a DEM (its a square of ~45 pixels, only). So, if your area is VERY limited, yes, you can create a useful DEM. Otherwise, the 3D surface will be barely usable, depending on your expectations...
