[SCRIPTING] [RMVX ACE] SCRIPT REQUEST: EXP SCREEN/LOOT SCREEN, AND A SHOP.

Hi everyone, I'll get right too it.
I'm looking for a script that would satisfy Three needs
1. After a battle, instead of the normal ending, you instead move to a screen where you gain your EXP, and can then spend it on skills (Which I intend to be variables) as currency. After you are done spending your EXP, you go to the loot screen and you choose which loot you want to take from the enemies, and you are able to drop items from your inventory from this screen.
2. Mostly the same as the Loot screen, but after you open a chest.
3. There are two types of shops, item and skill. In the Item shop you can buy things (That the merchant has, such as weapons) from what looks like the loot screen, and in the skill shop you can but new skills (That the merchant has up to the level he can teach you that skill) from a screen that looks like the EXP screen talked about earlier.
Would it be better to do this with eventing, and if so, how?
Thank you for your time! I looked around a bit, but I didn't find anything that looked like what I was looking for.

That is kind of what I would need, except that it would have a menu of your inventory as well, which you can drop. And you can select which items to take, instead of having to take them all.

Also, JP don't really seem like the same thing.
