your weather down in Houston isn't that much different than mine is up here in Fort Worth with the exception of the high humitidy...I had great luck with the Bhuts/Nagas last year...got about 2 pounds a plant if I remember correctly...
the key is, of course starting early...what you will find is that the Bhuts (and most of the other chinense) will stop setting pods about the middle to end of July and won't start pod set again until September when the weather cools a bit...from what I have read (and found it to be true), once the night time temperatures do not drop below 80F, the pollen becomes sterile...
120-150 days from transplant is probably a good rule of thumb for pod production, but you have to add in the down time in the summer, so say 160-180 days from transplant...it is the middle of march...if you plant now, you will be transplanting to larger containers (I use 3" square for my first transplant), in a month, so that is the middle of April...another month puts them into 5 gallon containers for their second and final transplant, so that puts your plant out about the middle of May...this is where the 160-180 days start....figure the middle of November you will have pods and another few weeks for pod production/harvesting...we get our first freeze up here in Fort Worth about the end of the first week of December (5th, 6th, or 7th) and that ends the season...you won't get a freeze that early down in Houston as a general rule....
what all my rambling is trying to say is "Yes, plant those suckers now".....
I don't know how you are equiped with your growing setup since you are a newby...I am a dirt farmer that grows exclusively in 5 gallon containers...it just works for me...
figure out what kind of seed starting setup you are going to use and what you have available...something as simple as a heavy duty cardboard box large enough to hold your starting trays with an incandescent light bulb for heat will work...just have to be careful with the heat, wiring and fire hazard...if you are handy with a saw and screwdriver or hammer, you could build one out of thin plywood (1/4")...if you do build one, remember, you need some air circulation also once the seedlings start to come up and you also need to pour the light to them to keep them from getting "leggy"....
IMO, the number one thing for Bhut seed germination is temperature and moisture...you want to keep the seeds as close to constant 85F as you can and you want to keep the seed starting medium damp, not soaking...
