I usually purchase frozen from reptile expos to save on shipping. As the collection has grown though I have been breeding rats to cut down on feeder costs.
I thaw my rats over night in the fridge and then leave in the snake room for about an hour before feeding with a quick shot from a hair dryer to warm.
Butcher paper is fine as long as you can maintain proper humidity. Which if you are using a tank will be a challenge. I would recommend something such as eco earth to help maintain humidity.
I do use tongs for feeding as I do not want to stress my snake if it accidentally misses and tags me instead of the rat. They are just standard grilling tongs. I do not use a hook though.
One thing I would not want to give up at this point is my racks. They maintain temp. and humidity so well it would be impossible for me to go back to anything else.
I do leave the snake alone for a while after I first purchase. It helps to acclimate to the new environment. They are plenty stressed out as it is and I see no reason to increase that stress. Plenty of time to play later. Typically 2 weeks for me with only interaction is to feed and clean.
Don't forget to quarantine once you get more than one! It can save lives! And we all get more than one.
