should I just scrap it all and take up farming now?

ItemManager:
Have you used the GetInstance Methode?

Why cant't you just add and remove directly from the Array?

Admittedly no. To be honest I wasn't sure what that method was for.

fnt_ItemManager p_ItemManager = new fnt_ItemManager();

fnt_ItemManager p_ItemManager = yourenamespace.fnt_ItemManager.GetInstance();

UserControl something = new UserControl(ItemManager);

private theItemManager itemManager;

public UserControl (theItemManager item)
{
    itemManager = item;
}
