Justin, I am not sure exactly where you are located, but we do not have a great deal of densely wooded areas in NC TX unfortunately. There are patches like the Heard (in McKinney), LLELA (in Lewisville), Cedarhill State Park (not very birdy), Ft Worth Nature Center. Then there are some city parks that are fairly wooded - Bob Woodruff in Allen (it may be in Richardson, I cannot remember), Campion Trails (in Irving), River Legacy in Arlington, etc. As far as books (aside from a couple of good field guides), I would recommend the new TOS Handbook of the Birds of Texas. If you are after historical data "Birds of North Central Texas" by Pulich may be of interest. He also published a book on Tarrant county. I have both and value them.
As far as rare birds in NCTX, we don't have any particular species that winters here that is rare. Not sure exactly what you are after, but reading the Texbirds list serve is often a great source of information about rarities or unusual species, as are the Ft Worth & Dallas Audubon web sites. They are interactive. You can also check Facebook Texbirds for info. As far as most birded spots - eBird will be the best source of info for this.
Your requests almost make me think you are doing a paper! I hope this helped some.
