I personally wouldn't house a tiny baby in a 29 gallon long. If you want a tank - go with a 10 gallon with two tight hides. Here's what I personally use for my babies - it's a 15 quart tub from Dollar General. Heating pad has since been replaced by flexwatt and a thermostat.
Additionally, you might consider purchasing a nice male from a breeder rather than the pet store. Pet stores are usually imports, and imports this late in the season generally aren't as healthy as ones imported earlier in the year and certainly not as healthy as one you can get from a reputable breeder!
