What do i need to get started?

What you need depends on what kind of setup you're going for. You can use a 20L tank for sure, but you could also use a plastic sterilite tub from Walmart that would be a lot cheaper. As for the heat, if your room temps are pretty steady, you should be able to use just the UTH and ditch the lamp all together. Heat lamps often do more harm than good because they only serve to raise the ambient temps in the enclosure, but suck the humidity out of the air while doing so. As for thermometers and hygrometers, you don't need two of each. You can buy an Accu-Rite weather station from Walmart for about $11 that has a probe to measure hot side temps, and sensors on the unit itself to measure the cool side temp and ambient humidity. With just the one unit, you will be able to measure all the necessary temps and humidity. For heating, if you are going to use a UTH (under tank heater), you also need to consider a means to regulate the temperatures. Those UTHs can get up to 120-130 degrees, which is hot enough to burn your snake. Ideally, you should get a thermostat to hook the heat element into so as to control the maximum temperature it will reach. You can go with a top-of-the-line thermostat if you can afford it (Helix, Herpstat, etc) or for a single enclosure you could go with a cheaper one such as the Repti-therm 500R, or even use a rheostat or dimmer switch as long as you constantly monitor the temps. 2 identical hides are recommended for tank setups as it offers security for your bp, but some keepers use rack systems or tubs and either offer a single hide or none at all. That will ultimately depend on your snake's preference. You do NOT need a separate feeding container at all. It is purely myth that you need to remove your bp from their enclosure to feed. In fact, moving the snake to feed only causes unnecessary stress to the snake and can trigger food refusals or regurgitation, which is really stressful and bad for your snake. Substrate can be as simple as using paper towels or newspaper, if you don't mind the looks. If you're looking for something more natural, you can go with aspen, cypress, or coconut husk. Just make sure with a substrate like that, you are spot cleaning when needed and doing a full bedding change every 4-6 weeks so you avoid bacteria growth... Beechwood is primarily for decoration and can be used as something for the snake to rub against during shedding, but isn't a necessity...
