thinkpad x230t questions after getting it

hi
just got my thinkpad x230t recently
its awesome almost like a portable desktop you can write on
and i'm starting to play with hardware for the first time

honestly i'm having trouble finding screwdrivers to fit
1/4"x4" screwdriver is too big
3/16"x4" screwdriver only works with 1 screw
what screwdrivers do you use to open the x230t?

question
looking to upgrade ram on my tablet p.c.
Amazon.com: Corsair Vengeance Laptop Memory Kit 16 GB (2x8 GB) DDR3 1600MHz CL10 PC3 12800 (CMSX16GX3M2A1600C10): Computers & Accessories
is this the fastest sodimm ddr3 16gb 2x8gb ram there is?

question
if i wanted to add a second ssd to the ultrabase series 3;
Amazon.com: Thinkpad Sata HD Bay Adapter 3: Computers & Accessories
would that work with the thinkpad x230t?

question
if i wanted to add a second ssd to the ultrabase series 3;
amazon dot com/Thinkpad-Sata-HD-Bay-Adapter/dp/B002HKFE2K/
would that work with the thinkpad x230t?

question
any videos of anyone getting a 9mm ssd to fit x230t?
should i attempt fitting a 9mm or get this 7mm?
is a 9mm better and can it hold more?
will the ultrabase series 3 or battery slice fit after it?

also is this a good sata to usb? links to better ones?
Newegg.com - Vantec 2.5"/3.5"/5.25" SATA/IDE to USB 2.0 Adapter - Model CB-ISATAU2

any help appreciated thanks!!
