And to color them, the temporal particles to pathline filter has particles and pathlines separated. If you select solid color for either/both of them, you can change it to what you like.
Also if you are having trouble viewing a large set of point data, perhaps view them using the point sprites plugin. Load this in the Tools > Manage Plugins.
