As for your joystick issue. Most vendors in Australia tend to sell the MCA joysticks (which I personally hate but that's just me) and these sticks come in the colours you are after. They have a restrictor plate on the bottom to change from 8 to 4 way but it isn't as user friendly as Ultimarc's sticks and has to be changed over with a screwdriver.
Shoot Andy at Ultimarc an e-mail and see if he can get the balltops for the T-Stick/J Stick in yellow. He has the other 3 colours you are after and I know he was trying to find another source.
The only other 4/8 way switchable stick I know of is the Omni-Stick (Basic and Prodigy) but they have even less colour choices.
