For both 1. and 2. the spec defines association transformation. For example you want to associate process variable x.someParameter to your task data input xIn:

<bpmn2:dataInputAssociation id="_ta2cskLFEeGV7InrpvHmpg"> 
<bpmn2:transformation xsi:type="bpmn2:tFormalExpression" id="_ta2cs0LFEeGV7InrpvHmpg">x.someParameter</bpmn2:transformation> 

Even tho you can specify these type of transformations in the jBPM Web Designer easily (in the assignment portion for example you would do "x.someParameter->xIn", you would have to test this in the runtime. Alternatives would be for example to use on-Entry/Exit scripts, script tasks, or if you are using domain-specific nodes you can do any transformation in your executeWorkitem method with plain Java.
