Reinstalling display drivers on Y580.

Hey guys how's it going?

I recently put in an SSD and put Windows 7 on it. I put the original HDD in a external hard drive enclosure. I went through the Lenovo Drivers Partition and did as many as I could.

I have a few questions:
1) When going inside the Lenovo Partition I just clicked setup for all the drivers. I didn't go any further than clicking on the folders of "AHCI, Audio, Bluetooth, etc..." Should I go exploring and go inside each individual folder? For example the VGA has Intel and Nvidia and I installed both. In the Nvidia Folder I clicked "setup.exe" and installed it. Is that all I have to do or do I also have to go inside "Display.Driver" and "Display.NView."

2) The problem is that even though I downloaded the latest Beta Nvidia drivers 3xx.xx in the control panel I do not have the display tab.

3) Anything else I should do after installing the drivers? How can I optimize to get my computer faster boot time than 25seconds (my latest boot time). It's a Samsung 64gb SSD. 25 seconds is awesome but is it possible to make it faster?

EDIT: ADDED ONE MORE:
4) Is it possible to use my Laptop Monitor as my 2nd monitor and use my External as my 1st Primary Monitor? Is this possible? I ask because I am using Steam Big Picture and when I have steam on the external it doesn't stay there. I click Big Picture when I am in fullscreen on the external. When I click Big Picture it goes immediately back to my laptop's main screen. I looked on Steam forums but I can't find a fix.

Thanks guys!
