If you want to hold your points but snap your lines, in your geodatabase topology you can vary the tolerance after setting the points as the priority, and any line endpoints closer than the tolerance to the point will be moved to it.
Alternately you could use the Integrate tool to do something similar.
Do both on copies or make backups since either changes the input dataset.
ET Geowizards has a polyline global snap wizard it is not one of the free functions.
If you are okay with moving the points to snap to the lines there are several other options. Google on "ArcGIS batch snap lines" to get many suggestions including using the Near tool, some Arcscripts and Hawth's Analysis Tools. Hawth's tools won't work in 10x unless you have installed VBA but their successor tools, Geospatial Modeling Environment, should.
