Welcome, sounds like you're in good hands.
As far as lighting goes, I bought some brilliant fluro T5 "under bench lighting" from bunnings - they're around 80 cms long, one fluro, have a switch and housing - and my plants never looked greener.
(get to know me, and you'll realize I'm an expert at killing plants) these were cheap and have just about turned me into a plant expert.
Sailfin mollies are pretty amazing to watch, the rest - well I don't really know much about, unless they're betta splenden, or betta splenden.
Have you considered a betta female sorority? Pretty colourful, hardy and smart... you could even look at some angels in with them.
Looking forward to photos! go get a photobucket account and share the love.
