UV is recommended as it improves redox potential. Not a must have but good to run 4-6 hours a day. It will prevent green water and kill whatever microbe lurks in the water waiting for fish to be stressed so it can do some damage.
Depending on how much light you're putting in, you WILL have to use fertilizer also. The LFS is a poor source of information as they usually tell you that you need to buy something. Not why and if you need it.
A CO2 system does not have much importance which. You need a CO2 canister, tubing, pressure reducer, solenoid valve, bubble counter and reactor/diffuser.
I don't see a bad choice in there. Can you elaborate on that part?
