Alright, so if I don't clear and only do Unrevoked3 as it shows in this video it won't reset my device, it will only create a backup and root, correct? That's what I was thinking but I got confused when someone started talking about needing to get temporary to back up files first before going full root. The post was just in regards to if I wanted to do a full reset prior to rooting.. that makes sense now. I may do all this later and may even opt for a custom ROM but for now I have a few little issues I want to take care of and don't have tons of time to devote. I appreciate you telling me there are ROMs that will keep the UI Sense because that helps me to realize I may want to do this once again.. just not right now. If I could find a ROM that was like what I have now w/the battery percentage on the battery, made it so that the LED could be adjusted or simply disabled when charging (annoying when on dock at night) and a few other simple things w/o losing 4G or stability then I'm interested.
Well I don't know what video you are looking at, but if you follow the guide and just don't do the step (section 1: Prerooting) where it asks you to factory reset your phone you will be fine. Just start at Section 2 of the guide, however I would highly recommend reading over it all, if you haven't.
MikFroyo hands down will give you everything your little heart could desire and probably much, much more.
Trust me when I tell you this, you will save yourself much more time in the long run if you just factory reset and flash a custom ROM with all the settings you like from the get go. Just my 2 cents though, I'll say it again to each their own. That's the beauty of our phones, so many options. Here's the link to MikFroyo and the link to his thread on xda is here.Enjoy and if you have any other questions along the way feel free to post, many here willing to help. Also if you haven't read the OP, be sure to read it.
