Buffering Points and Polygons

I am looking for help as to what to plug into the buffer params to get accurate results. 

What values should I pass to the buffer service to accurately create a 100 foot buffer around a polygon or polyline when the inSR and ourSR equal 101200?

Looking at the API, if the bufferSR is GCS then the units has to be in decimal degress, however this is a project coordinate system.

Do I have to change the bufferSR to something other than 102100?
Do I have to set the geodesic to true?
Do I have to re-project the geometry first and then perform the buffer?
