Need Fairly Advanced Script Help!

[PixelHurricane]

First of all, please only answer what you know.
Second, don't just give me this site. I know it and use it, I need to know what functions in it i need.

Spoiler below!

Lastly, if you can solve the problem from a different approach then mine, by all means tell me!

Now for my problem list.

• I need to have a certain entity move at a velocity. example: have a box fly at the player from a stand still position
  
• I also need to have an entity move with the players view. example: simulate the player dragging something in a cut scene.
• and last but not least I need to have a flash to obstruct vision. example: like the flashback type flash but faster and not triggering a cut scene
  

If you can help me with any of these it would be much appreciated!
EDIT: I am not a noob to the editor, so please don't respond like I am one.
