The documentation says
SDL_SRCCOLORKEY and SDL_SRCALPHA
will only work if the surface is in video memory. So does this mean if I want
to do a colorkey blt or alpha blend from system memory to video, Im going to
have to write up the routines myself? If so is SDL going to have routines to do
this soon?

Sorry, that should be “is only accelerated if the surface is in video memory”
It works just fine with system memory surfaces.
