Landing 747-400

What is the proper landing speed (IAS) for the 747-400 with full flaps? Also, what is the proper flare angle at that speed?

Speed around 145 - 155... flare pitch.. 4 - 6 degrees

At that speed with flaps fully deployed, the 747 pitches up about 10 degrees just to stay in the air. If I lower the nose to 5 degrees the VS descent plows me into the runway.

What's the trick?

Depends on weight but flaps 30, 240k kg 140kts
280k kg 152kts
320k kg 163kts
400k kg 184kts

A little bit of light tech talk to help you understand the nose high attitude better. As airspeed decreases the wing will generate less lift. In order to create the lift required to balance weight (Newtons law equal and opposite reactions/ forces in flight) we need to increase speed or the angle of attack. The reason you are nose high in my opinion is that the speed for the weight is too low. Try an approach at a higher speed...ie 170kts and see if this helps.

You flare by looking out the window not by instrument indications. There is no specific pitch indication to try for when landing. Correct speed and technique will ensure proper landing attitude.
