no problem, everyone starts somewhere. Right now i'm running Tranquility 3.0. By far this is my favorite. I've tried rubix blurry and focused, apex, fly x, and SSX. All were nice, if I had to pick one besides tranquility it would be Rubix. Make sure you know what your installing though, especially if it's a blurless rom. A lot of the features that you might be used to/like on your phone now may not be available on roms like Rubix focused, apex, and fission. These roms are as close as you'll get to an aosp rom for the X. SSX has a great look to it, and a lot of detail was definitely was put into it by the dev, but it slowed the performance of my phone, and my battery didn't do too well. Although it's like a theme and a rom all in one with SSX. I chose Tranquility because of it's convenience of not having to wipe my data. It is also very responsive, and my battery does well. What you need to do is make a backup of what you have, hopefully you made a backup of your unthemed stock rom but oh well if you didn't. Then start installing whichever roms you'd like to try. Give em a few days to a week, see how you like it, if you truly hate it, flash your backup. Do that until you find something that suits you. Hope you enjoyed this haha, my .02
