1 : Are spline based curves not allowed in automation ? and is the resolution of 1024 steps enough when logic claims sample accurate automation ?

What are "spline based curves?" I find the fader automation adequate, but not fantastic. I do most of my automation at the object level through the use of splitting tracks and raising or lowering levels there. That is where the real power of Samplitude lies...

2: I want to use stereo sidechaining but can't see a way to do so in the same way as in cubase e.g. crunchessor. Are only the builtin effects allowed for surround configurations ?

Sidechaining isn't in Samp unfortunately. Someday perhaps? You can only put the built in effects on the surround masters, but you can put any effect on an individual surround channel- Native, VST or DX.
