Vertical movement, shooting + other issues

[TXC]

Hello everybody, I'm new to bB and have been working on this project and trying to figure out how to:

 

1. Make the green sprite move vertically, towards my ship;
2. Set missile to vertical position;
3. Make a zap shot for player sprite (as in the game Solar Storm, for example);

4. Add more sprites (enemies, walls, etc.) with different movement patterns.

Any help would be appreciated

PS: When "READY!!" shows, press down to start the game.
