Replacing failing hard drive (the original 500GB one )

I would like to buy a 1TB ssd drive to replace said failing HD, after having the local apple store guys diagnose it as such ... and am set to buy all parts including the solid state drive from IFIXIT, and do the work myself. This is the 13" late 2011 unibody Macbook-pro laptop.

I own no tools yet, except for the mini-phillips for removing the back face of the laptop.

So, my question is:

Do I just buy the ssd part sans fixit kit, but add the spudger and torx wrench into the cart with it, or do I buy the SSD with fixit kit, and rely on it to include said spudger/torx parts?
