Ty for the indebth reply

i have one more noob question, what is the best root out right now for the TB? Also is the different sms/mms that the bionic jas apart of the different UI it comes with?
I can't answer the first, I'm running stock unrooted and quite happy getting my UI jollies with Go Launcher.
But, yes, SMS/MMS apps are part of the UI that each phone has chosen. If you don't like the native SMS/MMS app in Sense, there are TONS of SMS/MMS apps, and many are free.
The beauty of Android is that, by and large, it's modular. HTC chose a bunch of apps for you and built them in, but that does NOT mean you need to use them exclusively.
The SMS/MMS libraries behind the scenes are separate from the application you use to get to them. So just go find an SMS/MMS app you like better and start using that. HTC focused on fixing the underlying problem of SMS/MMS being sent to the wrong person in this release - so you can focus on finding a UI that looks nice.
Same with the camera app - HTC added support in the OS for the front-facing camera and fixed up the messed-up camera libraries. If you don't like the native camera app, download one you DO like and put its shortcut where the camera shortcut is now.
I'm using Go Launcher for my main launcher, QuickPic for my gallery management, and a few other apps to replace apps that I don't like as much from HTC. You're free to do the same and make the phone look how YOU want it to look, no root or custom ROM required.
If you want to start changing things like notifications and deeper parts of the OS, or remove apps that HTC or Verizon have forced on you, or stuff like that - then you can look into rooting.
But don't forget - once you've gone custom ROM, it's YOUR responsibility to look for security updates and apply them as needed. And that usually means a complete wipe of the phone and a reload of a new ROM. Verizon is currently doing all that work for you. Don't minimize the amount of effort involved in doing that yourself - it's an ongoing undertaking. In return, you get complete control over your phone and the ability to customize anything you want. Even to the point of breaking your phone if you mess it up.
Honestly, I'd encourage you to start with non-root stuff if you're just looking to update the look and feel of the phone. Try out Go Launcher. Load a different keyboard (I use Thumb Keyboard 4 with a very colorful skin to make it look all snazzy). Get a new camera app. Try out a different SMS/MMS app. Get some neat backgrounds. Add a better weather app like BeWeather. You don't need root for ANY of this, and most of it is free.
