Welcome! I'm very happy that you have come here to get advice before your Lil one shows up.
1. I use eco earth in my tank set up and paper towels in my tub set ups. Both work fine. Paper towels are cheaper just not as astheticly pleasing.
2. Most of us use an accurite digital indoor outdoor probed thermometer to measure our temps. You can find them at walmart for about 12 $.
3. I used to think tanks were the Way to go until I found out about using tubs. There is a great thread on here by one of our members that shows how to properly set up s tub. They are cheap being about 5-10 for the tub. Compared to 50+for a tank.
Hopefully someone can link you to that thread and to our care sheet. Those two will tell you everything you pretty much need to know.
Good luck!
