40 watt is fine. The Daylight Blue isn't necessary unless you plan on having live plants. It will be pretty bright too. You can use it for now and later get a Exo Terra Sun Glo with concentrated beam. Always use some sort of fake plant for cover and security when using heat lamps.
You want a lamp with dimmer switch so that good. You may also want to buy a timer for your lights so that your frog has a 12 hour day/night cycle. Just set the timer to say 8 am to 8 pm. Then switch bulbs.
