Samsung Galaxy S3 (Straight Talk, Build H1) Jelly Bean 4.1.2 to 4.4 KitKat

So I've successfully rooted my Samsung Galaxy S3 from Straight Talk using TowelRoot and have installed SuperSU. I now want to upgarde to KitKat 4.4, but don't know where to start? I've done alot of reading on this and I understand I have to basically download a ROM of KitKat 4.4, but I am wary as to which one to download and how I go about installing it. I don't want to brick my phone.

If that's not possible or too dangerous, I would at least like to remove all the stock bloatware that came with my phone. My baseband/build number ends in H1, if that is relevant at all.

Thanks!

CyanogenMod 10 (Jelly bean) for Xperia E1

Good morning , I wanted a version of CyanogenMod 11 stable for my mobile , but unfortunately is not yet stable , but I always liked more the CM 10 (Jelly Bean) and I have a lot of free time, I would ( try to ) make a version of CyanogenMod 10 for my device , but gave me a question : If the default system is the KitKat , it is possible to do this " Downgrade " with a custom ROM ? It is possible to make the CM 10 to a device that was "born" with kitkat ? Thank you ( sorry for my bad English , I'm using google translator , I am Brazilian ) and my phone's model number is a D2004 / D2005 and am currently using the Cheetah ROM
