whatsup20, If possible do not try to update your new players firmware as it can lead to all sorts of problems and your player may become unusable.
If your player uses the Sigmatel chipset I suggest you try SMV video format. You can download a SMV converter here:

I am not fully familiar with sigmatel firmware so can not help with the language settings, generally all the options available are in the Settings>Language area where you have looked.
To access the equalizer settings try pressing the menu button while music is playing and see if there is an equalizer setting there.
