I live in Goodlettsville, so I'm not too far away from you. I would be happy to answer questions regarding plants and plant-related issues (substrate, planting, lighting, CO2, etc), if you would like. The most local forum that I have been able to find is:
Everyone is really nice on that forum as well, but topics are pretty much cichlid related and not about plants.
I, too, would be happy to send you some plants during warmer weather. I have a ton of different species growing in a high tech set up. You seem to have really nice plants, too! Sometimes, it is better to read up on things and try some things on your own as well. That's how most of us became "experts"= through trial and error over a long time!
