I just wan't what's easiest to setup >.<
Get the crucial M4 kit like I linked before.

You could also bump up to the 256GB, I'd recommend at least that, 128GB is not very much, but to each their own.
The kit includes a little USB cable right in the box, plug your SSD into that and then plug that into your MacBook Pro. Then, go to disk utility, select your new Crucial M4, click 'restore' and select 'Macintosh HD' as the source. Give it a few minutes, then when it's done, shut down the MBP and swap out the factory drive with the SSD. It should boot right up like like it did before (only faster)
