Very cool fish, will look nice with the plants (like any other anabantid I suppose).
There are hundreds of different lighting sources that cover a huge array of prices that will work as long as you have a few things in line and can be creative with your solutions.
K Rating stands for Kelvin rating and (as any photographer can tell you) is a temperature scale of how warm or cool the light looks (don't think "OW that's hot! Think warm and cool colors from middle school art). Natural Daylight is around 6,000K; and appears bluish. "Daylight Bulbs" will come anywhere from 6,000 to 7,200K. Plant Grow bulbs are usually between 5,000 and 7,200. This just has to do with the colors the light is and how it utilizes the different colors plants need. I use 6,500 K bulbs in some of my smaller tanks and a combination of 7,200K and 5,000K over most of my larger (not because I am picky, but because the lights that come for larger tanks often have these combos in them).
You also have to think of the bulb itself. You can get daylight bulbs in CFL form and most other kinds of fluorescent bulb. Now they even make plant bulbs that will fit in shop lights (I wonder what people are growing with THOSE).
A super general rule that tends to work for tanks of that size (and some going either way) is watts per gallon. Most lowlight plants can be grown from 1.5wpg to 2wpg (some, like mosses, even lower).
Good news with these plants are you rarely need fertilizer and substrate usually doesn't matter. With substrate the smaller the grain size, the better roots can establish (like sand as opposed to big rocks).
Check out
Nova T-5 Extremes lighting (Check the link, I can't remember what size 29g are but I think they are around the size I linked... they come in other sizes though. This would be you over 2wpg). They are affordable and very efficient. They have good reflectors (I like t-5 lighting for this, the bulb size doesn't block a lot of the light reflection).

This guide is helpful in finding plants that suit the lights you want. Sorry for my string of ridiculously long posts lately, but I hope it helps you out.
