Please at least use basic punctuation, it's hard to follow your posts like this.
Anyway, to install the latest stable nVidia drivers, you can use this PPA
. But be warned that many users reported that they can not see anything after reboot with Optimus. I have no experience myself with this, but would it be possible to install and configure bumblebee before rebooting, or disable the integrated GPU before you get everything running?
All in all, nVidia w/ Optimus and Linux are a rough combo. Luckily, nVidia did say something about supporting Optimus on Linux in the future.
