Nice tank! =] Looks like a... 10g? It has a lot of potential for plant life, you could really make that thing flourish.
As for lights and gadgets.. as you have seen from my journal, the key to a prospering NPT is light. Do not
get sold on those expensive $110 LED Marineland strips. All you need is, in you're situation, probably one CFL 6500k+ light in a lamp with decent PAR rating. I got my lamps at Lowe's for $4 each I think, and the two CFL light pack was maybe $10. As for the heater, this is the exact heater I am using - http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
It got awesome reviews and I've read of it not breaking down. Really don't go cheap on the heater.. especially in a cold climate. The heater was the first thing I bought because back when it was only me, Clare and that little 1/2g fish bowl, she almost died in the winter time.. in Arizona. I never want to have her or my girls at risk again! That heater is so good I've considered buying another. Its gone down in price too, when I bought it I think it was $35.
Other than that I have a Tetra whisper pump I am absolutely happy with, a 2 way gang valve (but I really only recommend one air stone/air outlet), and a Hyrdo 2 sponge filter which is awesome. The pump was $10 and the sponge filter was $12. Another $5 for the gang vale and probably $7 for connectors/hose. A lot of my struggle with tank and plant life was water movement.. neither betta's or plants like a lot of movement. I had to take out my Coliseum's air stone and turn my filter's air output WAY down. With my future 5/10g male tank I'm going to buy the exact same setup I have with my sorority.
