First; YOU DON'T NEED TO SHOUT! We're here for you, kitty. {friendly scratch behind ears}

Amen on the external filter, but I'd go for a cannister variety because if you set it up right there's less surface agitation to drive off your CO2. (you
are using CO2, right?)
Again, amen on the plant selections, but I'd also throw in a Java Fern v. Windelov just to add another leaf shape. Also, if you've got enough light, dwarf sag for a foreground "lawn" plant; if not, Java Moss might do.
I seem to remember that you didn't want a green-only plant aquarium, so I'd get wendtii v. red for one of your crypts (that
is a low grower, right? Mine is small and I can't tell) and "tropic sunset" for the hygro.
