[Q] Paranoid Android, Rom and Kernel, doubt topic

hello people, I am Brazilian and I do not speak English law, so I'm with the Google translator assistance, I hope that even understand that!
Let's cut to the chase, I set up a rom on my I-9100 [S2]. But how do not understand roms exchange and much less kernels, wanted to know if this rom:
Build Version: 4.45
Build Date: 07/29/2014

Size: 155.35 MB

MD5: e5e6d3e1e05c325be2ec4014c80d227b

File: pa_i9100-4.45-20140729.zip
Accompanies Kernel for i-9100.
And if you do not follow I install the rom without problems?
(A question, this version of android is the 4.4.4? Or 4.4.2? Sorry about the lack of knowledge!)
THE PARANOID ANDROID ROM! :o
