Please I am in some need of some major help!!!

I just started useing RPG maker 2003, and i was woundering how do do some things.

1. I don't know how to do the chest action (Were you click on a chest, take its item and it is never pickup-able again)

2. Some Charsets (usable people) are haveing a green or pink or just some kind of color square around them and i cant seem to get it off of them

3. In 2003 is there anything like a Limit Break or a Trance that i can use for my charecters?
