I'm new too, so I can't offer much, but I've found a few trail resources useful.
1) AllTrails app for your phone. Incredible for finding & looking at trail reviews, from hiking to 4x4. Maps are interactive, downloadable, and reviews can include maps with pictures along the route (for current condition updates).
And it's free, with paid features (I haven't found anything I wanted it to do that it doesn't for free though, so don't worry)
2) Traildamage.com - I heard this was fantastic but it's a full paid site now. Granted, it's only $1 for the first year...I'm too cheap lol YMMV
As for mods...Google is your friend. There's tons out there for very little money, DIY, etc.
Welcome! I suggest you buy the FunTreks Guide books for Colorado. They are an excellent resource and you will get plenty of value from them. Buy both the "Guide to Colorado Backroads and 4Wheel Drive Trails" and the Northern Colorado book.
Welcome from Parker! This is a great group of people and they are always here to help you and give you a hard time about light bars and going to "the mall" but it's all in good fun and there is a lot of combined experience on this forum so soak it all in!
