Im making a game and i need some help!

Hi i am now trying to make a complete rpg game i have already made some games but i am trying to make a very complete game.
On the begining of my game i though it would be nice to put a name on the character so there will be a box where you type your name and you press a button that says ok and it transferes the name to the character by this action script:on (release) {
_parent.textBox2.text = _parent.textBox.text;
_parent.scroll2._visible = (_parent.textBox2.maxscroll > 1);
}
is this action script ok or there are better ways on doing that?

So i want my character to move and im putting it this action script: onClipEvent (load) { moveSpeed = 10;}onClipEvent (enterFrame) { if (Key.isDown(Key.RIGHT)) { this._x += moveSpeed; } else if (Key.isDown(Key.UP)) { this._y -= 0; } else if (Key.isDown(Key.DOWN) && !fall) { this._y += 0; } else if (Key.isDown(Key.LEFT)) { this._x -= moveSpeed; }}onClipEvent (enterFrame) { if (Key.isDown(Key.SPACE) && !jumping) { vel_y = 36; jumping = true; } if (jumping == true) { vel_y -= 2; if (vel_y<=-15) { vel_y = -15; } this._y -= vel_y; } if (_root.ground.hitTest(this._x, this._y+35, true)) { vel_y = 0; jumping = false; }}onClipEvent (enterFrame) { this._y += 16; if (_root.ground.hitTest(this._x, this._y+1, true)) { this._y -= 16; }}

And i want my background to move too so i will put this action script:onClipEvent (load) {
movespeed = 7;
}
onClipEvent (enterFrame) {
if (Key.isDown(Key.RIGHT)) {
_x-= movespeed;
}
if (Key.isDown(Key.LEFT)) {
_x+= movespeed;
}
}
After that i would like to have some enemies that move and attack me so if my character would have 50 HP the enemy takes me off 1HP and if i get to 0 die, how would the action script be?

After that i would like to attack to the monster, i need an action script for that.

i would also like the enemy to drop a coin and put it on an itemslot( i tried alredy but i just can’t understand it)

I also wanted to do this: if you step on a certain place you would go to another screen.

I would like to have a store where i can buy stuff and when i buy something the store takes the money the item costed and that item appears on some of my itemslots

Thanx guys sorry if it sounds like i want you to do all work but i been trying to find tutorials and the one on kirupa is horrible.
Thanx for the answers!!!
