Alot of people go for non-co2, low light 29 gallon tanks. Less costly to maintain and the plants can still look good.
Some plants that usually work well are anubis, crypts, java moss, java fern and others. You can find lists all over the web, including this forum of low light plants. In terms of lighting you can get a dual T5 normal output, a dual T5 High Output and raise it above the tank, get a single T5 High output light or DIY a fixture.
If you are set on doing Co2, you could do a dual T5 High output light not raised.
