I was thinking on drilling 2 rows of holes 1 inch apart around the tub (the second row will be about 1/2-1 inch below the first.) Im not sure of a diamater for the holes yet.

Would that be a good idea?

Also would putting 1 or 2 rows with the spacing above be good on the lid aswell?

Would this provide good air flow?
I use a soldering iron to melt my holes. You can get them at Wal-Mart or Lowes for about $7. It's quick and easy and will punch about a 1/8" hole. You can also drill them if you want.
The things that will affect the humidity are:
1) Number of holes.
2) Size of holes.
3) Ventilation.
4) Size of water bowl.
5) Substrate.
6) Depending on where you live, ambient humidity can also play a factor.
You can punch as many holes as you want or need. I like mine neat so I use the same pattern on all of my tubs. I put 2 rows on the front and 2 rows on the back. None on the ends and none on top. I space the holes on each row 2 inches apart. For the top row I mark each of the odd numbers on my ruler(1,3,5, etc) then for the second row I mark all of the even numbers(2,4,6,etc) This just offsets the holes and is my preference. After your initial holes, if you find that the humidity is too low, you may need to cover some holes or if it is too high, you may need to add a few. You can also use a fan to help regulate humidity by adjusting the airflow through the tub. Personally I use a small oscillating fan. During the winter, I run it on Low or not at all, depending on the humidity. During the summer, I have to run it on a higher speed to keep the humidity down.

I also forgot to ask this in the main post but will the locking handles that come on some rubbermaids be a good enough lock
A proper sized UTH will help keep the temps stable. If you live somewhere with a significant temp drop, you may want to use a UTH that covers about 1/2 of the floorspace.

If you get a digital thermostat, you just set it to the temp you want the UTH to run at and it will turn the UTH on/off as needed. There are several types and styles of thermostats, depending on your needs. For 1 tub, a good basic thermostat is the Hydrofarm. It will cost you about $25-$30:

The locking handles are good, but I would recommend picking up some binder clips at Staples or Wal-mart. These will close any gap between the lid and tub. I also use straps on my tubs, which may be overkill, but I'm paranoid like that. Most people don't use them, but some will use them instead of binder clips. It's pretty much your preference. I'll make another reply with pics of how I set my tubs up.
