1)If you wish remove camera shake, select cam control layer in scene, double hit U button (to see all animation) and remove all wiggle expression, for example it looks like wiggle(1,15). 2)If you need add extra lines, you need copy particular and light layer together. For example select Particular main1 and Main1 after just copy and paste this layers in same scene. Now go to copied particular layer>effect controls>Emitter(master)>Light Naming>Choose Names button>Type new name for Light Emitter Name Starts With. This name must mutch with light layer name (f.e.Main1, Plus1,Plus2, ect). Now adjust light layer trajectory for new line. 3)All lines settings in particular layers, all lines trajectory in light layers.

Thank you!

One more question, is it possible to make the lines run into and becomes a logo?

Unfortunately no, need to create new technique for this.
