You came to the right place to get good advice -- I've found great help and support here! I have a newly started (February) 29 gallon as well, and I'm still using the lights that came with the tank while I save up for upgrades.
I'm planning to replace my plastic hood and light strip with a glass top and a 65w Coralife fixture, and to add DIY CO2 of some sort in the next few months, but for the moment my plants are limping along with Flourish and the Flourite in my substrate (I did a mix of Flourite and black gravel). When I upgrade the lights and get the CO2, I will lose the bubbles that I have going from a bubble wand -- but in the meantime, the fish seem to enjoy them, so I'm leaving it running.
Just FYI in case you're wondering how your plants will do while you wait to upgrade your lights or add CO2, I have found that my java fern is doing quite well (putting out plantlets and new leaves from the rhizomes) and my wisteria and swordplant are growing slowly, but the new growth seems healthy and the plants have put down big, strong root systems. My cabomba is a disaster, though.
It looks like your tank's off to a great start -- I look forward to seeing both of our 29's evolve over time! (By the way, I have danios and swordtails in my tank as well -- and a few otos and ghost shrimp).
