Homebrew PCBs

I was actually thinking of bypassing that whole portion of the 
schematic and just hard-wiring two wall warts into the schematic at the 
right voltage (15v and 5v).  Just not sure if the diode served some 
other purpose (like adjusting the amps?).

Do you have any recommendations for the two parts from elfa I listed?  
After looking at the schematic, and seeing what the power portion does, 
are there parts you would substitute?
