1) Cut and paste into the next frame:
   if(this.hitTest(_root."player's instance name")){
       gotoAndPlay(2);
   }
Now change the frame number and the player's instance name.
Put stop(); in all of your frames.

2)Draw all of the frames you want in the player's Sprite. Then, Put stop();on the frames you want it to stop at. Then, in the stage click on you'r character and on the enterFrame part put in _root.this.gotoAndPlay(the frame that the move animation is in) right underneath the _x+= 10; type codes in your character.

I'll upload some stuff to Dezerith.

Your questions are intensely high-level, and part of programming is thinking down to the mechanics that will make it go. I suggest reading more on programming in general to get the effects you want. For example, with an inventory, you can just have empty mc's that change to a picture of the item on the next frame, have an array that holds flags for those items, and a variable that tells you what item the player selects.
