for the power mosfets. The originals are ST microelectronics number BYW98 200 fast recovery diodes. These are rated at 200 volts. I would like to upgrade these with 400volt units but some I am running across are ultra fast recovery. Would using the ultra fast recovery units cause a problem if I were to use them?
The mosfets I will be using are Fairchild FQP17N40.

The answer depends on the characterisitcs and the application.
In many cases, the use of the ultra fast diodes will not be a problem, but you need to look at the recovery energy, voltage drop etc.
