Maybe it's time to stop looking for something and create something by yourself? :)
The systems you are looking for are not complicated, they require minimum knowledge of LUA / C++
Since you can't maintain a good pServer relying only on shared scripts. This is just a friendly advise.
The first can be easily done by creating a custom item in our SQL generator.
And simple implementation of Eluna
Use a PLAYER_EVENT_ON_LOGIN hook with function if player has item : http://eluna.emudevs.com/Player/HasItem.html
Now you can do everything you wan't when you checked if player has an item (vip token) or however you call it.
The second script you are looking for can be done easily in C++ since i don't see any chance of change experience rates for player with Eluna. there might be one, we should ask creators of it.
but if you take a look at that outdated scripts you can make your own you need without any problems.
Sorry i'm not the type that creates scripts for people , i'm the type to help them create one.
