I've also got a 46 gallon bowtank. I can make a few suggestions.
To start with, I do think you're a little overloaded with fish. Also, the 6 line Wrasse and Mandarin are NOT going to work out...unfortunately. As was mentioned above, the Wrasse will eat the same food that the Mandarin HAS to have. The Mandarin is a slow, deliberate hunter. The Wrasse is a very quick eater and will quickly eat all the pods that the Mandarin needs to survive. Also, with only 40 lbs of Live Rock, you'll be hard pressed to keep enough pods growing for the Mandarin, even without the Wrasse in there.
As for lighting...it would appear that you're wanting some of the easier corals to keep, which would include soft corals and some LPS. You're also wanting an anemone. A fairly good source of light for soft corals and LPS would be Compact Fluorescents. A 2X96 watt unit would give you plenty of lighting for soft corals and LPS and will be fine for a Bubble Tip Anemone. A lot of people will tell you different but I've had a RBTA in my 46 with PC lighting for over a year. It's thriving and very healthy. An even better source of lighting would be T5HO lighting. That would be great for any Anemone and would allow you to keep most SPS species of corals as well. T5HO would also be adequate for some Clams. The 3 VHO's on an Icecap 660 should be adequate for what you're wanting as well though.
Instead of having 1 400 GPH power head, you'd be better off with 2 or more power heads. That way you'll be able to get more random flow instead of a single source of linear flow. Even if you were to get 2 or 3 Maxijet 1200s, you could aim them in ways to create great random flow.
As was mentioned above, do a lot of reading. There's a lot of great information available on this forum. Another source of great information is
