Yes congrats indeed. I have not seen such determination from a bidder in a long time!!
Personally, I do no much care for care sheets, but here goes.
Keep your sling in that tub for the next two instars. The substrate must never dry out completely, but must never be soaked. It must have a perch. Don't be surprised if it makes a little burrow at the base, it will climb up to the top on occasion (after dark) to wait for food. Always be careful when opening the tub (or any enclosure), it might be hiding under the lid.
Temperature must never drop below 20 degrees and never rise above 29 degrees. They do not like extremes. Feed it once or twice a week. It will take small crickets, I am not sure about small roaches but it might eat those as well. You will find that the tub has five rather good holes in the lid. They will not thrive if the air becomes stagnant. Opening the tub twice a week to feed also serves to refresh the micro environment inside the tub. Remove uneaten items without delay.
Re home into an medium sized arboreal enclosure after two molts. Make the substrate shallow and the perch high, then follow the guidelines above !!
Good luck !!
