Im not sure you would need a lot of the things you posted. A basic setup can be done with a 10-20-30gal aquarium, and setup very basic. To start out keeping it simple is a good idea.
You may want to read though some of the following:
For a very simple tank you could start with a 15gal standard, 2-3 inches of leca in the bottom, covered with Jungle Mix, or other substrate. Then add plants and leaves for cover. Use a full glass lid and seal the edges of the back to keep the ffs and frogs in.
As for tricolors they are a bold and great frog. The only concern I would have with them as a beginner frog is that they are a big smaller and extremely fast. If done right it is not a huge issue but trying to put them in the tank can be tough and or move them if needed.
I hope that helps a bit...
