So there’s tons of good info on the LOTRO forums related to wardens.  I will start to post my own thoughts here as we go but figured I’d toss out some of the better links as we go:

Also, each class section on the forums has their own RSS feed, so if you use a feed reader (I use FeedDemon myself) you can subscribe to the Warden forums.  There’s a ton of good info and it is a pretty decent community, just make sure you try to search a bit before asking questions like “how should I trait, or what weapon is the best?”
