New owner needing help

[theJuju]

Okay, so let me make a list of everything that it looks like I need to change.

1) Buy an accu-rite digital thermometer/hygrometer from Walmart for around $15 to replace the cheap dial one at the top of the cage. This will measure both the cool and warm sides of the cage.

2) Get rid of both the day heat lamp and the purple nighttime heat lamp. Get an under the tank heating source, such as Flexwatt, perhaps. If I get Flexwatt, what size should I get? Does anyone have specific recommendations as to product, size, and wattage?

3) Get a second hide rock. Does the one I have in the current setup I posted above look too big? My BP seems to like it well enough, but I don't know if a second one of those will fit in the current setup. I thought it was a plenty big enough tank until she got to adult size, but I don't know how to make everything fit. Also, does it look like the water dish is big enough?

4) Either cover the current screen top with aluminum foil, leaving some ventilation space, or get a plexiglass lid for a 20 gallon long tank. I'd prefer something more aesthetically pleasing than the foil, but I don't know where to get a secure plexiglass lid, or how much it would be.

5) Buy some aquarium background and leave only one side of the tank uncovered, that way my BP has security.

Is that everything?

Also, what should first priority? Even something like spending an extra $15 a week will really throw off my budget, so I've got to try and fix this stuff over the course of a couple of weeks. =/

Thanks so much!!

Oh, and mr.spooky, thanks so much! Ya, I'm pretty fond of Knoxville, and I live about 2 minutes from fins n skins. I'll stop by there Monday or Tuesday.
