Some questions

Infared spot bulb: How long should this be on? Should I leave it on 24 hours on the hot side or connect it to my timer?

You don't need an infrared bulb for your snake, the only reason people use them is because they want to be able to see the snake at night but I'm assuming you don't stay awake at night lol

Temps: What are the ideal temps and humidities for both hot and cool sides? I've done plenty of research and reading, but I want to hear from you guys as well.

Hot spot should be about 90° F, humidity should be around 50-60% on normal days and when in shed, try your best to keep it up around 70%

Scales: My BP seems to have what I might describe as partial sheds? There are parts of his body that feel like shedding but it hasn't really started yet.

Bump up the humidity by misting his enclosure, and dampen a rag and allow him to slither through it a few times. Do not I repeat DO NOT ever pull of shed. If it is really stuck and not meant to come off and you pull it off, it will absolutely do more harm than good. If your humidity is correct, it will come of with the next shed.

Age: How can I tell the age? The previous owner said he was young, and I can tell he is, but I'd like a little bit better of an idea.

You can't really tell unless you know the hatch date. It could be a power fed baby, in which case it would be bigger than it's supposed to, or it could be severely underfed, in which case it would be WAY too small for it's age.

Hide: I put his secondary hide on the UTH. Is this a good idea? Is it okay? I also put the probe from my electronic therm in here is as well to. I've got an analog therm here on the hot side as well. Should I move the probe the UV spot?

I don't really understand this question. You should have a probe thermometer measuring the temp on the hot side, and that's all. Do you have a thermostat controlling the UTH?

UTH : I was a little skeptical about this. I have the small ZooMed heater. Is there a way to regulate the temp other than watching it? I have it connected to my adjuster just in case it gets too hot, but should I hook the adjuster to the UV spot instead?

Again, get rid of the UV spot. Snakes do not need UV light. They are nocturnal by nature, so they are never exposed to natural sunlight. It's just not necessary. It doesn't help the snake at all in any way. You need to have a thermostat hooked up to that heading pad, if you don't, turn it off right now until you get a thermostat because it will burn your snake if you don't have a thermostat. Hope this helps.
