Everything sounds good, but they don't grow that slow. He/she will outgrow a ten gallon in about six months MAX. I keep my temps around 90-92 on the hot side and low 80's on the cool. I would definitely go with a bci for a first boa cause bcc's require a bit more care and precision in fluxing temps (which a tank won't work for)...they also can be a bit more of a handful than most common bci's.
