Hi Plug 1.
Im not sure what you mean by
" I'm not gonna use any of the ripped off, nulled crap out there"
On your concern of loosing everything
Backing up WordPress
go to your dashboard
Be sure you are using the most current WordPress version.
To do that see your WordPress dashboard in the at a glance it shows the version and will prompt you to update if needed.
On changing themes in WordPress the only time I have had any issues when changing WordPress themes is with a theme that is not compatible with the current version of WordPress. Usually due to its writer not keeping updated.
Also, you may find that you need to modify your header pic or images that wont fit into the new theme.
You can always switch back to the theme that you had if you find that the one you chose doesn't act like you want.
Like perhaps the plugins you had been using suddenly quit when you changed.
You will find in the top right hand corner of your WordPress dashboard there is a help pull down.
From your sites WordPress dashboard
To change your WordPress theme
Click Appearance located on the sidebar
Click Themes from the pop up
choose add new or if you have themes that you have already downloaded choose one of those
