Hi Jian,
for 1.) have a look at my liggghts text- and binary reader at
http://web678.public1.linz.at/Drupal/?q=node/681 (you have to register
to see the attached files) as a starting point for your own implemention.
for 2.) you can use the PointSprite Plugin, I've written a HowTo here:

greez,
Christian
