Just rooted my S4 active....now what do i do?

[vic38]

I just switched over from the iPhone. I'd like to be able to install custom themes I've downloaded on my computer. It was a lot easier on the iPhone, I have no clue what I'm doing. I already rooted my phone using this How To Root Samsung Galaxy S4 Active - AndroidTeen I then downloaded Goomanager, but I can't find a TWRP recovery that will install. I don't want to ruin this phone, so any help will be greatly appreciated. I'm completely lost on this.

Let me know if you manage to put the Google Edition ROM on there.
