Unhappy [Q] URGENT ACE 2 i8160P

My name is Jose Angel and I am from Spain. I would go from 2.3.6 to 4.X in my Galaxy Ace 2 NFC I8160P but I'm newbie and do not understand much. I'm afraid. I do not understand much English, I'm lost.

The first thing I did was follow this video ()
and now I SuperSU, but is not what it does.
I kept looking and found the famous xda forum to which he had never entered.
Now I'm downloading gapps-jb-20130813-signed.zip and 10.2-cm-20140228-UNOFFICIAL-codinap.zip.

Could you help with installation?
They are as follows:

Put the zip files on your SDCard
Reboot on Recovery
Wipe Data / Factory Reset
Select "Install Zip from the External Storage"
Choose CM zip file
Choose gapps zip file
Reboot to system

I followed the steps, but nothing happened. Follow Android 2.3.6 but now I can not open Google Play and SuperSU and other applications that were already (such as weather)

*Help URGENT - ACE 2 I8160P III

I'm terrified. I formatted the phone and still not working SuperSU, Google Play and application preinstalled weather. Tell me you know the solution, which is hopeless. I am very worried

Thank you so much for everything and sorry if there are errors in English.
I await your response as a last option
