Thanks! I purchased all but the ludwigia, aponogetons, java fern and moss from aquaticgarden.com. I don't use ferts at the moment, but I'm considering to do so in the future.
UPDATES: Upped the ante! The lighting is now at 3wpg. Nothing major has died, so I'm happy about that. The gourami has been pulling up the rotala every now and then, but not such a big deal when they root. A few yellowed leaves on the crypt, but still looking good.
