If you want to use a variable number of attractors to deform a surface, my guess is that at some point, you will have to be able to do some looping like in the .net script in the definition i provided. It may be possible without scripting but this might become very complex, because if you want to test the distance from the attractors to the points on your surface, with GH you can only get a huge list where ALL the distances from the points to the attractors will be stored. David Rutten already said that the next grasshopper release might be able to manage multi-dimensional lists, in that case you will get a "list of lists" and in that case it might be easier to sort the results, but my guess is that right now, doing some scripting is the easiest and simplest way to go and concerning the boolean operations, check out wikipedia for a start, and try them out for yourself http://en.wikipedia.org/wiki/Boolean_algebra_(logic)
