That's a really nice start!
I'd recommend (when it runs out) replacing the leaf zone with either Flourish Comprehensive or even getting some ferts from forum members. While I'm not a fert expert, I know that leaf zone only has a couple of the many nutrients that plants want and it's very watered down. I just got some from Nilocg. Look in the for sale section and he has a Back in Black post and I got the first item listed. There are also liquid fertz down the page that you mix yourself with filtered water and I can say that it's way better than leaf zone. Since you have low light plants I'd suggest using half of the recommended dose of fertz bought from forum members.
The light looks ok for the plants you bought. if you get higher light plants, then you can look maybe into an LED fixture like the planted+ by finnex. I personally think it'd do well on your tank since it's so tall. Light will be low at your substrate as it is.
I worry about the rasboras and your betta. I'd just watch for fin nipping. I know rasboras aren't as bad as tetras, but ever fish is different.
Other than that, I think you're off to a great start.
My advise is advise, and not meant to be taken as a professional opinion. I'm still new but hope this helps.
