Hey hows it goin AP?
If you're getting a hatchie or yearling then it seems most people use click clacks. There's a lot of debate about it recently but I use them and have found them to be very easy. Plus I noticed a thread the other day where some one had put their young olive in an enclosure and it damaged it's prefrontal scale sticking it's nose between the sliding glass. That may not have happened in a click clack.
Put the tub over 1/3 of the heat mat. I use heat chords as mats seem to have a bad reputation, though it's been said they are a lot better now days. I keep mine heated 24/7 until they are big enough to go into their adult enclosures. And feed them year round. Make sure you use a probe thermostat with your heat mat too.
Lighting in the enclosure (not click clack) is up for debate. I don't give my pythons UV. I have a small fluro in each enclosure with a normal cool white tube in it, which is just for light. I use ceramic heat emmitters for heat that just screw into the standard es light fitting like a globe.
