Can you tell me what else I need?

Okay so I already posted pics of my big boy (still nameless) and you guys helped me figure out he is actually a blood. Anyways, right now he is in a 55g tank his temps are like 86 degrees during the day and id say 78-80 degrees at night with his heat pad and a towel covering most the lid, he has a nice hide he fits into and a water bowl he can fit into. I ordered 8ft of flexwatt tape 4", a thermostat (an alife 1000w), the metal connecter things but no plastic insulaters because I plan on soldering, and some hatchrite for the near future if plans go okay. We are getting a female from a breeder down here close to us so maybe we will have some babies soon. :) I would like to build a rack to fit my 106 qt tubs (are those big enough???) or build custom melamine enclosures. Can you tell me what I'm missing or what else I should get before setting them up in a rack?

Any info will help!

Thank you!
